B303 cam in so to ho conversion?
Reply #20 –
I had an E303 in my least engine with the flat top pistons.It was really close with PTV clearance.I wouldn't go any bigger,and new valve springs are a must.I also had ported E-7 heads.I was really pushing the limits.It worked great and made great power. BUT,just because it worked on mine doesn't mean it'll work with yours.Find some H.O pistons with valve reliefs,or,just use an H.O cam and good heads with 1.7 roller rockers.That will surprise you on what an H.O can can do for you.I think they are under rated by many people. If you can get the E-cam or B-cam for cheap,do it and shelve it until you have all the right parts.You really need Mass Air for either cam as well.Start collecting parts until you have what you need and do it right the first time.If you get in a hurry with this,you'll be worse off than think and hate it......a lot.
