Yes I know. Maybe I should just go solid roller that I will have completely redone heads totally different camshafts totally different lifters totally different pushrods and totally different rockers and totally different intakes and hope for the best then none of the Parts are the same from the heads up

Hope you used the copper antisieze and not the gray stuff. The copper works better in marine!

Put a 741 or 651 cam in it and be done with it. Easy on valvetrain and proven results over and over again.

Too late for all that.

When heads are flowed cam will be discussed.

Oh, and Tim, MER dyno tested a 509ci with stainless marine manifolds , and dyno headers back to back yesterday. 639hp with dyno headers , and 602hp with stainless marine manifolds.

Your exhaust sucks too.:helmet:

Ya I know, and it seems I'm standing on "that side" of the fence now, sucks to see this happen but I guess it is what it is, not fun to be kicked when down after so much effort, most guys would have tossed the towel long ago... I won't give up and gonna see what round 3 does... If I fail I will address it then.

I think I'm gonna rely on my plan I had from the beginning of this and go with it. That's just how it is now

Otherwise that one that howards had that was mentioned about 50 pages ago. Nothing wild and around 243/249,253-640/640. Think MT posted an article on it.

I used the two part system. I think it's made by JB Weld.

Tim, for what it's worth you saved me a chit ton of money and headache with your saga. Even through the cat clawing in this thread it's a wealth of information.

Would one be able to use their Johnson lifters with good success? Or what would you recommend?
