Which company's kit would you recommend or to buy individual parts ?
Is it lower cost to buy a kit ?

My Dove engine is .030 over, would you suggest staying with it or higher ?

What kind of power could it be ?
Kev, given your situation I think you made the best choice. I'd talk to Barry @ Survival Motorsports or Blykins about a rotating assembly. Given your heads (not the best) I'd think somewhere between 500 and 550 hp would be reasonable. Go with an Hydraulic Roller cam, not a solid roller or any flat tappet. You'll appreciate the HP and reduced maintenance. If you were trying to extract every drop of power AND had a very light rotating assembly (high $$) then a solid roller would be the best power ticket.

Kevin,

A 0.030 over block does not leave much room for another overbore. More significantly, the additional overbore doesn't give you much more displacement or power.

If you are looking for additional low speed torque and power to raise the car's fun factor you ought to consider the bigger bore 427 block (still with a stroker). Talk to Brent (blykins) about what you want from the engine and let him build one for you. That is really the short way home in terms of money you spend and results you get.

Check out Brent's website. He doesn't show as many different engines (including dyno results) as he used to, but he can no doubt build you a great engine.

BTW, check out his FE rocker arms, good for building a 7,500 RPM hydraulic roller FE.

I'd be scared as hell with an 0.050" overbore. The ONLY way I'd touch or even consider a block like this would be with a very detailed sonic bore test.

No, but Brent Lykins (CC member name 'blykins') will know them intimately. He may weigh in on this thread, but I wouldn't hesitate to give him a call if I was in your shoes.
