What are your plans for the car, street, street/strip, or strip only? I'm guessing this is in a Chevelle, but what car? Looks like a high RPM type engine, if you're planning mostly street you will probably want to make some changes.


Welcome to TC.

street and strip it's in a 80 camaro it came out of a 68 chevelle

It's a real strong engine, but it will be pretty rowdy on the street. What are you looking for as far as driveability, a street car that does good at the track or a track car that you can tolerate on the street?

a street car that haul ass on the track!!!
do u think it will b better with aftermarket oval port heads?

How much timing retard do you use for the 2 stage shot? 12.5:1 with a 150 shot x2 is huge! I would think that on the street a lower compression would be great and use the N2O on the track. The best 402 setup I have used before was 9.5:1 on the street and it was great. I used 781 GM heads.

about 6.deg's i don't use it on the street..the motor ran 7.86 1/8 mile in a 68 chevelle ss with 2.25 pipes all the way out...with a smaller cam 525 lift with a smaller stall 3000 tci........without the gas........ i have not sprayed it yet..
