I'm still trying to decide on a combination to build a mid 300hp for my 65 Studebaker.

After pondering the combinations on Ryans car pages. I've pretty much rulled out a 400.

Would I be better off to put my $ in to some good heads and just rebuild the stock 350 rotating assembly, new hypereutectic flat top pistons. Will this support the hp?

or should I go for the 383 balanced rotating assembly. If I do this I'll be out of budget and will have to use my stock heads that I may attempt to port.

Already have Holley 750cfm, Edelbrock performer intake 2101
