Title: sbc head coparison and charts
Post by: Swims350 on August 16, 2010, 01:20:47 pm

I just done a quick search on some small block chevy head stuff and came up with some good info and charts figured I'd pass it along.

That is some helpful info.  I used to always compare engine combos to that "ryanscarpage".

I was gonna post of the link to mortec which shows most of the head and block casting numbers, but it looks like the site has been shut down.

I go to chevymania.com all the time for casting numbers for heads, intakes, cranks, blocks, suffix you name it.

This is another good one. It was from this article that I chose to buy the Dart Iron Eagle heads (same as the 'Aerohead Racing' heads they test, which are the Darts).
