Carbureted LSX forum - well it is going to happen now.

Well I have been on here before and always dreamed about the LS swap after much disappointment in what i had I finally fell into a smoking deal on an LS motor.

Car is a 70 nova that will be getting an LS3. I'm sure I'll be turning to you guys for help. The engine will be on E85 since i already have the carb and fuel system for it from my last swap.

Sweet, the old small blocks suck... LOL. I will never look back.

the hardest part is i went from a well thought out 468 big block in my 69 vette to a VERY poor small block when i got this nova. old big block went 6.71 @107 in the 1/8 with 3.25 gears and 28 inch tall tires N/A 10:1 468 custom cam dart heads. this small block is a 11.7:1 265 273 @ .050 solid roller afr210 eliminator heads with the wrong springs wouldn't RPM and had NO torque from that big ass cam and low compression.

Well, your big block went .4 fater than my stock lq4 and 10 mph faster with me pushing a manual Trans, that is allot of induction and cubes for a small difference in performance to a stock truck motor, lol.

yup but it was a TON better then the current junk...... That's why I'm doing the ls3

Oh and that was on a 275 street tire not a drag radial

The best party about it was that it was a real nice combo.... 490 ft/lbs at 3000 and 499 @6000 with a peak of 540...... 229 236 @ 50 cam. Just a real nice combo.... I'm looking for a nice combo again..... This will get boost via centrifugal blower down the line.

Yes sir, a procharger is destined for my RS with the 6.0 stocker.
