Thinking of replacing my street tuned iron 427S/O + iron MR heads with a more radical street/strip spec. all alloy Pond or Genesis 482 unit with either 2x4 holley intake or EFI stacks - either way 600+ hp.
Who in your opinion / experience is the best engine builder in the US in terms of cost, quality products and service? Keith Craft & Survival Motorsports seem to get good reviews but are there any others I should consider?
Thanks
Stuart
