Return on investment!
I know everyone hates these types of questions, but... If you take a stock 78 I-6 w/ approx 55-60k on stock rebuilt and add:
Does a different cam add that much? If so what type is best to retain, but enhance the built in characteristics of the I-6. Would I need to change the stock rockers and push rods?
I have heard conflicting views about adding larger valves than stock issued. What is the final verdict and is it worth it?
Thanks....New to this and I would like to spend my money wisely, if there is such a thing.
- Headman headers into a single 2.5" pipe w/ a decent muffler
- Edelbrock 500 performer
- Offy d/p
- better dist w/coil

I'm guessing about 220 hp and 315 lbs. That's off the top of my head though and probably a bad guess at that. Anywayz i'd have someone with a desktop dyno run it if i were you. I'd swap the cam out too it all depends on what kind of performence you want. wether it be down low torque upper rpm speed or just the choppy idle sound. You can still stick with your stock rockers and pushrods i would think too.

since the rebuilt only has 55-60k, I should be able to just R&R the cam and lifters and keep the rockers and pushrods, right? I'd like to keep the tork down low, but would a new cam make that much of a diff?
