Thread: 383 blower mtr build?

Tweet

I Have just finished building a 385 stroker ( 40 over 350 with 3.750 crank).
I went with 4 bolt main, eagle steel crank and 5.7 eagle rods. i used srp dished blower piston and with the dart pro1 215 72 cc heads it came out with about 8.1 to 1 compresion. running A doug herbert blower roller cam with 630 lift.
i installed a weiand 8-71 with 2 demon 750 blower carbs. still running the blower 14 % under making about 10-12 lbs boost.the car starts and runs great, idles fine in traffic. not sure of the horsepower, but i would guess about 700 right now. i have a snow performance methanal injection system i am going to install so i can run more boost and timing. the engine is in a tubbed out 76 chev elcamino. i have a turbo 400 with 3800 stall, ford 9 wihch is apart right now as i am swapping out the 6.00 gears for some 4.88.
as far as cost the engine cost about 12-13 grand canadian so far..

I like it.
I don't think you need a 4.88 gear.
I would think with all the torque and hp you would need a 4.10 or a 4.33 gear.
