    I finally swapped out my buddies 350ci from my truck and swapped in my new fresh stoked 400ci. And for the first time ever, it not only started on the first spin but was exactly timed to 6 deg adv, idled at 800 rpm and not a single lifter tap. I went back and adjusted the lifters after the first 20 min breaking /oil change cycle, at most I had a few about 1/16 of a turn off. Anyone who builds small blocks knows that this is just a random fluke of chance unless your constantly repeating the same build up but I'm going to take it as a good sign!

    Anyway, the off the line power is astounding right off idle. The TSI torque low stall 4x4 convertor stalls higher than with the 350ci that was previously on it and it leaps to attention. The throttle is on the edge of being a little too snappy and I might tone it down a little. I can't wait to get through the break in period so I can open it up but have to say I'm already very happy with how it performs from 1000 to 3000 rpm. Feels like a big block. I'll post fuel mileage as soon as I get my speed-o working. I'd highly recommend this speed-o-motive stroker kit to anyone looking to build thier 400 !!! Oh, and I'll post engine opperating temperatures under load as well for those pessimists out there!

    The irony here is killing me, I was just looking through the pics of your fender trimming, front speaker, highlift / maglight / fire extinguisher mounts from another post and thinking to myself "I'm jealous!!!". Were did you get that mag light mount anyway?

    Very Very cool! Checked out some of the site too, very well documented. I dig the "Shop-vac" flowed heads ( a true gear-head - [​IMG]) I have been working on a Kenmore Wispertone flowed Q-jet. [​IMG] -

    Thanks! I'm all about building my own equipment. I'd like to hear more on your Kenmore Wispertone setup!

    Sweet, congrats on such a success!

    The flashlight mounts that I have (Use gave me the idea after seeing his pics, too) are MagLite mounting brackets (D-cell) that I got from True Value for about $7.

    You can see them <a target="_blank" href=http://www.maglite.com/product_acc.asp?id=092874359734534&amp;plc=DCELL&amp;psc=3DCELL>here</a>.

    its not that its weak its just not a 415 , not matter how gonzo u go there is no replacement for cubic displacement , period.

    I agree, raw cubes are fun!!! Gas mileage is much better than the previous 350ci which was nicely warmed over as well. A round trip of about 50 miles through mountain roads and city streets used to gobble down between 1/8th and 1/4 tank and the 415 used just over 1/16th of a tank. Thats including tugging the 350ci, engine stand, and cherry picker in the back for half the trip returning the previous motor to my good friend who loaned it to me. Those hills and streets that I used to open the secondaries on I now fly through partially into the primaries. Torque is my new best friend!!! Oh yeah, the temp was pegged dead center of the stock guage the whole trip, except the first 4 miles or so which worked up to center from cold. Even with 33's and 3.07's I'm rocketing up hills and leaping off the line! Lets see, another 420 miles untill I can open up the secondaries... sigh!

    No no no, none of that. We're not comparing my 305 to a 415. :) I was just responding to K10 Andy saying he didn't like his 305. I thought he was like me, we both seem to like ours.

    As to your 350, I can and have beat my friend's '96 K1500 shortbox in a race. He has a 6" Pro-Comp and 35" MT/Rs with the same trans and the same gearing. He has the Vortec 350. I would guess that an IFS shortbox weighs about the same as a solid axle one or less.

    As for your Blazer and its 350, if you want to come all the way down from Canada to race a vehicle that's probably 1,000 or more pounds lighter than yours to prove that your 350 is better, be my guest. :) I certainly don't have anything to prove. I'm happy with my 250 HP in a 5,000 lb. SWB pickup.

    But, K10 Andy is right...a 415 would rule!

    Had an unexpected bonus today. I locked the hubs and drove it out back of my work through a small of road area for the first time on the new engine. There were a few sandy uneven climbs that I used to have trouble with in the 350ci where I would have to get some speed to get up or I would start spinning but could never do it slow without digging in.

    Well the 415 crawled up them without any tire spin or speed with the tires aired up. Now I did also ditch my Holley 'Puddle Dumper' for the better Q-Jet but other than that, only the small blocks were swapped. That extra bottom end has made a huge difference in my traction and ability too keep from spinning (completely proportional to the right foot that is). Anyway, thought I'd share since I didn't expect such a drastic difference here.

    DUDE!!!!
    You have no idea how jelous i am.
    You know how long I've been set on that speed-o-motive 415 stroker kit!?!?
    Keep the reports coming on how you like that new 415 engine...
    I was planning on doing the same last summer until I blew all my money on my '67 Camaro... but thats got 469 cubes so I guess it's all good. Theres no replacement for displacement!!!
    Maybe this summer the K/5 will be getting the stroked 400 it deserves!
