Guys, I have a 67 Nova... about 3000 lbs. At present it has a low power 327 non-matching numbers. I'm wanting to replace the 327 with a stronger chevy crate engine. The problem is deciding how much power it can handle on the street. This car is NOT a daily driver, and NOT a strip car either.
I guess you would call it a street cruiser and local car show attendee. The problem is not having stop light to stop light power to keep the Mustang and ricer boys in rear view mirror,(sorry ford guys.
My Nova has a 10 bolt rearend with Richmond 373 gears, a pro-built TH350 with 256 first gear, new stock front end and new Competition Engineering Slide-A-Link in the rear end.
Which size crate engine would work best for me... 355, 383, 406, or a 421 chevy? My budget tops out at about $7,000. Thanks in advance for any info. and/or opinions. Steve Largo, Fl.

The 383 is a tough combination to beat when looking at power per dollar. With the right heads and valve train they can produce some very respectable numbers.... You didn't say if you have them or not, but with the added power a stroker engine makes it would also be good to tie the unibody together with some frame ties and maybe a 6 point roll bar. No reason to have a bunch of horsepressure if you can't hook it up...Yesterday is history, tomorrow is a mystery, Live for Today!

67 Nova, I have been a owner of a 1966 nova since 1988. The car will handle the power. The problem i had with High HP in my car is that the Front suspension, and Brakes are not good enough for high speed. So if you have the ability to not go to fast, then no problem. However, i know i dont. Upgrading the front suspension is on my " to do " list. I stopped driving mine about 13 years ago when my son was born, and it scared the hell out of me at about 110 mph. ( no he wasnt in the car with me ) Looking back on it i would have started with the suspension/ brake upgrade, and then went to the High HP. but those cars sure haul ass with a little power.
