Heres where a lot of my time and money go besides into my k5:
-'67 camaro RS/SS
-454 .070 over, steel crank, forged rods, forged je pistons, Performer RPM rectangular port heads, decked to 98 cc's to achieve 11:1 compression, heads lightly ported and polished inside and out by myself. ARP head studs and fasteners throughout.
-New CAM (I degreed in) and REV KIT: Crower custom grind SOLID ROLLER, 260 degrees duration @ .050, .590 lift, New valvesprings (212 in lbs. of seat pressure!) New pushrods, (lifters and pushrods weigh 44 grams less per set!!! Lightened up OVER 3/4 of a pound out of the valvtrain! :eek1: )
-1.7 scorpion roller rockers, Dart single plane manifold, Holley 920 cfm carb, hooker super comp 2-1/8" primaries to 3" & 1 chambers.
I also just put in a stock volume & pressure oil pump along with a windage tray, and a crank scraper to help control some oiling issues..
Oh yeah, rings gapped a little bigger for some juice and a sportsman fogger kit. :wink1:

It fired right up.. appearantly i know how to put together an engine and adjust a solid roller cam. ;) Only problem is its weeping a little outta the head studs, hopefully it should go away after a few heat cycles.
Should be making a little more power this time around. :D
 
glad to hear its back to gether after the fire and headache you went through,

love those big blocks!
 
Got any paddle tires for that thing....???? :D


:usaflag:

That there thing is perty. Really that is a nice looking ride you got there. Two questions. What HP rated NOS kit is that (250?)? And what size fuel line is that running into your regulator?

Very very nice looking setup
 
awesome man! what exactly do you do with the car? ever take is to the track?
 
Ryan, bottles are for babys. :D Lower the compression and drop a blower on that thing.

Ha! Yup yer one of those guys! So all the pro stock class guys are babys? :wink1:
I've already been dreaming about that, but the fact is this motor has gone waaaay too far to just "drop the compression and slap a blower on it".
That's my next engine build up. Even bigger, with a huge blower on it. Mudjunkie82 comes to mind. :thumb:
Kinda need a rollcage and all the other safety equipment at this point now though.. I know i'll be getting booted next time at the track.
Last time out on the hyd. roller cam it went 11.6 @ 118 with a 1.75 60'. I think it was good for a little more if i coulda gotten it to hook.

I caught it right as it was about to spin a bearing so i went through and put in all new bearings in the bottom end, new rings gapped a little bigger, a new solid roller cam with a rev kit for more power and the direct port nitrous are all the new goodies this time around.

The sportsman fogger is good for up to 250HP. I'll probably start at a 50 or 75 shot and SLOWLY work up from there reading plugs all the time, after the engine is dialed in. I'm not even thinking of hitting it until i have all sorts of goodies hooked up for it. Dual nitrous selenoids in case one sticks (they stick open! :eek1: ), purge solenoids, fuel pressure and oil pressure safety cutout switches, rpm window switch, wot switch and a button... its gonna be so redundant its not even funny. No progressive controller though because those duty cycle the solenoids and shorten the life of them (more likely to stick open).
The thing was scary before on just the motor, the direct port fogger is "just in case".
 
Hey Ryan just a word of advice, dont leave the tank in the trunk. I left mine in and it got hot one day and blew the safety valve, there went a tank of NOS. :doah:
 
Have you thought of installing a Positive Crankcase Ventelation system? Those valve cover breathers are not going to cut it. Many drag racers use a valve cover breather with a 5/8" hose coupler, which has some 5/8" heater hose coupled to the header collectors. The exhaust flow velocity leaving the headers pulls the built up crankcase gasses out with the exhaust.
