Re: GT40/GT40P on 289 windsor
From my dealings with an engine runing e7 ported heads with gtp valve gear..This set up including gtp springs, keepers and retainers are NOT up to high lift and rpm..This engine had 2031 Crane cam and 1:72 rockers..Which is possibly why valve head broke off as well...They're just not designed for this sort of treatment...
$3k would have got you into some NICE heads and valve gear too!!! Hope all is well now...
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
