[quote=snowman4839 If I switch rockers later, will I have to rebuy pushrods assuming I buy better pushrods for the stock rockers? Also what length and what type pushrods should I get? Same as stock since I have stock rockers? Are the stock ones cast or steel? Because I found these and they're steel and should fit http://www.summitracing.com/parts/cca-7861-8/overview/ The closest thing I can find in chromoly is 9.7" long instead of the stock 9.682" http://www.summitracing.com/parts/cca-7659-16/overview/
I called comp and lunati today. The guys at comp were kinda being dicks so I'm probably going to go with a lunati cam considering they gave a very similar recommendation. -219* intake/exhaust @ .5" -.5145" lift -114* lobe separation which sounded perfect to me. Only hiccup is Lunati said the installed height on the valve needed to be 1.85" for their associated spring with that cam. I just took the top half of the engine off today and am going to measure what the stock installed height is to see if I need to find longer valves for that spring. Do y'all happen to know the stock valve/spring installed height? When I call them back about the springs I'll ask them about the retainers and keepers.
I'm going to keep going through beater blocks until I find the right combination of good power and reliability. Then I'm going to invest my money in the original block and get forged internals so that it'll last for the forseeable future. If I can get it to run well and not bust a $200 beater stock block, then I can swap in forged internals with the same setup and never have to worry about the pistons breaking again.
Methanol injection will be after headwork and valvetrain but before internals. I'm wrapping up all the big things I want to do to it surprisingly. Got the turbo, fuel system, intercooler, and carb all done. Now I just have the big head machine work and later on meth injection and I'll be a happy camper.
His car was 310hp and 410ft/lbs I think. But I think he has another 600lbs on me with that turbo 400 over my saginaw 4 speed and his big block over my I6. It'll be close. [/quote]
If you have any galling or erosion on the tips of your pushrods, they should be replaced. You can reuse your stock pushrods, just check them out carefully.
Having greater valve spring pressure will tend to wear things out quickly if there are any defects.
Camshaft specs seem OK, but see if you can get a wider lobe center of 115-116 if possible.
Having forged pistons does not mean you cannot blow those up also like your last two engines. They just can take more abuse before they let go also.
Your dad will be surprised when you smoke him w/that V-8 of his.
What high octane are you going to use for your dual octane system? How about for the low octane? What are you going to do or use to keep the engine from blowing up on the low octane?
I do not remember if the intercooler seemed to help a lot w/power output on your 2nd engine?
