Ok so I am rebuilding my 292. Planning on decking the block, Pistons flush, accounting on a .040" gasket.

The heads are 5752-113 and I've read what I can find online "thanks Ted, John, Tim and everyone else posting info"

What I would like is some guidance to porting these heads. Is it true that they will flow 175cfm stock and may port out to 235cfm?

I won't need to go to far as I'm running a fairly mild cam 265-109 and eventually 1.6 rockers. I'm aiming at about 5200rpm if it goes further then that will be great.

So the porting to start with, match porting and cleaning any rough raised edges and what ever tips I can gain from you guys.

I understand induction works by volume and average diameter. Therefore if the average diameter was small and the port would then be long with an equal volume, the rev would be slow. yet alternatively a larger average dia. with eq. volume will rev quickly. Perhaps higher rev's too. So I don't want to flood the engine and expect it to rev to quick, yet some pazzaz to 5'500 will be great.

I am considering locking the orig. dizzy "load o matic" and running a Ez-EFI 2.0 carb. Love a mummets manifold yet difficult getting onto him, as I'm from Melbourne, Australia and E-mailing is my only option of contact, John.

So what its going in is a 55' Tbird 3speed stick build# 247 and gee it feels great to be cruising with the top down. I'll be glad to have it back on the road with in a month or two. I finally got my American classic convertible.

All the best, CK

Oh, Keep your wheels turning free!
