Stomis' 94 Street Truck - Snail Trail

One small trip for the truck, one giant leap in making it faster, lighter, better, and o more fuel efficient too.

Drove it 200 miles today to work 80 miles then 100 miles down to the junkyard since we got done early and then 20 miles home. I have to say its time for a change. Im sick of the sticking throttle cable. Im sick of the carb, really sick of the carb. Plus I got smoked screwin around with an old highschool buddy in this mid 90s cobra lol. Bad thoughts made me consider the turbo idea again lol.

But that said the motor has arrived. 130k-ish out of an 05 suburban with wiring harness and accessories. Im on the fence with what Im going to do now. I hate to flip flop like this but the money that headers and head work is going to cost me I could just pay for the turbo and make more through stock heads...

We'll see. Im going to crunch some numbers and give the machine shop a call to get a valve job quote.



 
drop it in and go . . . :thumb: don't be a web wheeler .

if you wana do some heads I got a set on a 4.8 . . . :whistle: hell I got the whole motor . . . :whistle:

What casting number are the heads and how many miles are on it. For what it costs to have a fresh bottom end Im going to do it. I always intended to rebuild it as Ive never had much luck with throwing junkyard parts in. Hell my 70k damn JY trans pops 3rd and 5th after I paid $500 for it...

The conservative plan was CNCd heads and a cam, 4.8 pistons for more compression while rebuild the bottom end, edelbrock intake and TB.
 
Junkyard **** sucks. I'd be weary too. I bought a 302 with supposedly only 100k on it, but when I pulled the pan there was 1/4 inch of copper in the sump. All the bearings were toast, but I got my money back.
 
I dont know what happened! 24 hours later and I think someone stuck a stick of dynamite in my 5.3!



Torn down 100% :D


Motor is flawless. Its amazing what not flooding the cylinders with fuel on the cold startup does for longevity in a modern motor.

Just took some shots of casting numbers etc.















I set the plans in stone. No more flip flopping. I'll build a ridiculous fast car when I finally get the 80 Malibu Ive always wanted. For now Im building a nice NA 5.3. Im hoping for nearly 500hp when all is said and done.

TSP 2.5 CNC LS6 heads

TSP torquer cam

4.8 flat tops and heads shaved for 11.5:1

ARP main studs, speed master head studs, Katech rod bolts (doing the rod bolts because I have a feeling this thing will live north of 7000rpms)

Ported ls6 oil pump

Double roller timing chain

Aftermarket or fbody oil pain

Edelbrock 90mm intake manifold and throttle body

SLP underdrive pulley
 
Got 99 problems but compression aint less than 11:1 :doah: :D



Pistons came in. Block going to machine shop tomorrow night. Planning on letting the guy measure up the pistons and then putting them on my rods, then having bearings ready to go to assemble the bottom end. Lead time on machine work is a week and a half sadly.


Only other updates are Im going with a Trickflow top end. 220/224 split grind with trick flow 205 heads. Little pricier than I was planning but for the $500 I'll have a much better, NEW head. Not to mention a combo with a great curve for 2000-6400. O and did I mention its independently dyno proven at 500hp with torque 300ftlb+ from 2200 on?

Im excited!
 
Should be a good time in that little truck.

Makes me want to start getting **** done on my 347 build.
 
Made some progress on the motor this weekend. Ive never had a terrible amount of engine build hands on experience and really wanted to change that. I know everything in theory but honestly the last time I built a motor I was 11 with my father and the machinist did 3/4 of the assembly work. I made it a point to do everything in my power to build this motor myself at my own shop. That being said I took the block over to the machinist to have it bored over, new cam bearings, and hot tanked.

Since I got my pistons in I wanted to make some sort of progress. Pressed the old dished pistons off the rods. Moved onto installing the rods onto the new flattop pistons. I have to say this is probably the first and last engine I will use interference wrist pins on. The $100 in machine work to have the rods honed out for full floating pins, and $50 more for later full floating pistons would have been worth it for assembly in my eyes. Again this is the first time I've done this but I busted out the mapp gas torch, lubed up the pistons, and heated up the small end of the rods to 400*ish. My first mistake was not making a jig for the pin depth so I had them installed evenly. At the end of the night I had 7 pistons with wrist pins that weren't properly centered in the piston and 1 with a pin only 2/3 of the way in from not being quick enough. Hasty on my part.

I really didnt want to swallow my pride and take them to the machine shop. Ive learned the error of my method (DONT ****ING RUSH) for the future but now I had to solve the dilemma I had gotten in. Since simply jigging the piston and pressing the pins back out ruins a cast piston. I knew I couldn't just remove and try again. I started doing a little research and found some links and photos of proper tooling to remove and install pins w/o destroying the piston in the press. At $500 that wasnt happening. Neither was ruining the pistons at $200 for a set. And to be quite frank I wasnt willing to concede. So out came the skills set that I am familiar with and started making a jig that would carry the rod in the press while I seated the wrist pins completely.

After about an hour, and a very smelly shop from quenching them in oil to try to deter bending here's what I had.





Although it bent on the second to last piston it served its purpose. Was my own damn fault too as I had forgot to lube up the pin with oil before putting it in the press on that second to last one... I plan on straightening it out and beefing up the "forks" to hold the pressure better. Basically what it did was go between the rod and the piston in the gap that the piston floats on. Since I was now supporting the rod where the strength and press fit actually is I was no longer exerting 10tons of force on the piston skirt ruining them. I saved my pistons and saved face lol :whistle:

So at the end of the morning that left me with 8 flat tops mounted on 8 cleaned up rods all assembly lubed and ready for the motor.





Wrapped them up and shoved them under the bench. Unfortunately I dont really have anything left to prep until the block is back. I need to do the wiring harness strip down and build a cam handle tool but other than that Im waiting. And that might be a good thing because I need to drop about $4000 to assemble this motor...


Ive been speaking with Comp Cams prior to my decision to go to trick flow heads. I told the guy I was looking at the trick flow cam and he suggested a grind they have very similar. I plugged it into cam quest and came up with 535hp and 460ish ftlbs. Thats crazy 5.3 numbers and still a daily driver quality motor. I dont want to say anything crazy here but the NA 5.3 record in a truck is 11.90. If my numbers are good thats roughly 420ish HP at the wheels and should be good for nearly a 11.50...
 
Got a little side tracked from the motor build and dropped $400 on a cowl hood. I went to the Englishtown swap meet hoping to get a real steal and save on shipping. Funny story sorta. Walked around for almost 3 hours. Every glass guy was sold out of hoods for my truck. Gave up and went to leave and my clutch push rod bent in half. Went back in to try and find someone to help me fix it and found the hood for my truck. Wife came and took me to the shop to make a new clutch rod. Lots of driving later we leave and I get a $55 ticket for loud exhaust. Asshole cops in town setup a check point, must still be pissed they couldnt get the track shut down.

But anywho. I got a 3in traditional style cowl hood. I was happy I found a 3in. IMO 2in isnt enough and 4in is goofy looking. It fits pretty good but not great. Im going to need to shim my fenders up in the front and shave the front lip down in the center a little. I missed driving behind a cowl hood so bad....






 
Well I got a price from a friend of a friend who owns a reputable body shop to shoot the truck in single stage for $500. Looks like it might wind up with a real paint job in the end!
 
Do you have more info on these trick flow heads for 500? Wonder how my 6.0 would like them.:whistle:
 
Yeah. Trick flow was basically the first company to offer a small aftermarket head geared towards 4.8/5.3s. The 317s that 6.0s come with will do 500hp easy cncd and cammed pretty easy. A set of trick flow 215s would make a 6.0 a torque monster I'd bet.
 
Busy busy busy. Going to Virginia to close on my house Friday. Should be picking up my block thursday night. Be home saturday, short side job, hopefully gap the rings and get the bottom end together maybe. Gotta order up some bearings.
 
Main and rod bearings ordered. Piston ring filer also.

Decided to stick with stock bolts on the rods and mains. ARP rod bolts require resizing and the KAtech bolts that dont are $200. It wont live past 6500rpms anyway so just money saved...
 
Busy weekend... Close on the house, drove home, hung out for 2 hours, then to the machine shop to pick my block up. Today I painted it and cleaned it to prep for assembly hopefully tomorrow.

I painted it with VHT Pearl Metallica Black. I really like it. Gives it some depth rather than plain old black. I just snapped some shots of it painted and cleaned. I definitely want to get the crank plastigaged and installed tomorrow. Onto rings after that. I picked up a ring grinder so it should be a piece of cake.








Moving along. Im not sure if the wife is going to want me to put the brakes on or just get it over with and in the truck with the house going on now...
