Sorry for the long story, tryin to get all the facts out
ok, so a couple months ago I took my 89 GT in for an MSD system install. The mechanic noted that after it was on she lobed more than she should and couldnt be timed to factory specs... The engine was rebuilt shortly before I bought it. Due to the timing problem and all he figures theres a pretty damn good after-market cam in there...
My question is if theres a way to determine the size of the engine w/o taking the upper manifold off? It doesnt seem to me to put in a hi out cam and not bore the engine. The only answer I've gotten is I can assume its a 5.3 b/c she takes 5.5 qrts of oil to fill her.
Thanks,
Breandan
