I'm guessing is a small block?any pics of the engine and wat are the specs?

Yes it,s a 350 ported vortec heads , flat top pistons , air gap intake and all i know right now the cam is a comps cam with the 4-7 swap , no pictures sorry

Cool. Should be fun, as long as it isn't at the end of its lifespan on that build.

A drag motor can and usually does have extremely high compression, as you can't usually burn a piston in 12 seconds. Racing cams knock the effective pressure down some due to high overlap. My race engine was 11.5 to 1, and I had to use race gas, $6.00 a gallon. It did smell nice, though. Racing valve springs have very high loading characteristics, so if it has a flat tappet cam, you will need to run Shell Rotella oil or additives to keep from wiping the cam. If you are going to drag race exclusively, I guess it's a wise choice, or just cruise on Friday nights, but for street use, you may find yourself regretting this swap.

The picture i guess is a little deceiving.The car is very streetable , it is not a drag only car it will run on pump gas just fine . We have been buddies for quite a few years so i know the motor pretty good.The motor is not that wild he just has a good engine tuner and an excellent drivetrain combo

The chassis of that nova is set up pretty well if he is running 1.66 60' times. By comparison, my stock '02 Trans Am runs a 2.20 60' on p245/50/16 street tires. A vortec headed 350 with flat tops will be in the 10.5:1 range, so pump gas is fine. I would be a little concerned about the intake manifold and cam choice going from the Nova to the heavier truck. I think the engine will lack the low end torque.
