I ran a 28x13.5 comfortably, which is a et street or a 325/50/15. Springs moved in 3" and tubbed. A 29" tire doesn't fit well without moving the rearend back. I tried a 29x15.5 but it was very very tight. They didn't really fit inside the wheel well. I had a 15x10 wheel with 6.5 backspace and...

Do you still have these lifters? Please email me at. [email protected]

I think that cam would fit your needs. I like that the cam apparently has a fast rate of lift, judging by the adv. duration and .050 duration and the lift is about as high as you would want to go. Check your clearances too.

I think easy 10.50-10.70's. I have heard nothing but good things about the 590cam.

More details please, but I would say easy low 11's with 500hp.

I stood corrected if you read my post again. I agree the heads may take it, just not the pistons. He needs to realize that piston to valve clearance is just as much an issue in his case.

Not with higher compression pistons they can't, especially with a hydraulic that requires preload. A zero deck piston without valve reliefs would doubtfully even fit a mp 509. The heads will likely take it but not the pistons. Last time my dad ran the 509 he had 1 valve bottoming out and wiped a...

That's a tough one. Used to be you just throw in some new lifters, but nowadays with cams going flat at the rate they are I don't know what to tell you other than live with it or try some new lifters?

Insuring the life of your motor is worth alot more than $1.60 per tank. I still have my doubts you are at an actual compression ratio of 10.6 and not pinging with iron heads and a 268 cam. I run 10.7 with edelbrocks and a 286 solid roller, 32 total timing and have made it ping on 91 octane on a...

If you only want 350-375 hp. the stock heads will be fine. You won't need 10.6 compression. I would build something similar to the 380hp crate motor specs.

I would never try to run 87 octane with 10.6 compression, especially with iron heads and a 268 degree cam. That would not even run well on 91 octane. The intake size of a head shouldn't be a concern when comparing 174 to 180 cc stock. The edelbrocks can flow alot more air and will make alot more...
