Top 5 performance mods that won't blow my motor.

[praisegeetarman]

1 HP/cubic inch is fairly doable with your 5 mods request.

1 - Headers
2 - Cam
3 - Intake
4 - Carb
5 - Decent ignition

For the numbers you want you might consider a off the shelf motor. By the time your do all the machine work and parts to rebuild yours you might be money ahead to buy a ready to go engine.

Okay. That does make sense. That was sorta along the lines I was thinking of. Thanks cat.

Good cylinder heads are important. praisegeetarman 1 HP per cubic inch would only be 327 HP. I do agree a crate engine would probably his best option

I will tell you first hand you'll be dumping some serious cash. I just built a 331 (327 bored .030 over) for my 65 Nova gasser. I started with a tired block, did machining, went with full rollers (cam, rockers, lifter), tunnel ram with dual quads, edelbrock performer rpm heads, plus all the accessories and I'm pushing about 500 hp. But I will tell you that my cost for parts and machining (as I did the assembly myself) was close to $5,000. Yes my Nova will run low 10's in the 1/4 mile and redline at 7,500 rpm...but going fast costs money period.

I changed his up a little but right idea.

And yes, your numbers are unreasonable for bolt ons. My Jimmy has a built 327 in it (large journal 4 bolt block, '69 large journal crank, bored .030) and it was in my camaro originally with all the mods. 10:1, double hump heads. It probably made 375 hp. 300 at the wheels. And it was NOT worn out. Needed more cam (see above Nova) and better heads.
