I've got a decent opportunity to pickup a 3FE with harness and computer from a mudder with a parting 80. I was planning to either build a 2FE for my truck...but more recently I was thinking of just doing rebuilding the head and having it shaved to bump the compression up a little and then run a sniper TBI. I picked up a set of 3FE exhaust manifolds already so I can get rid of the restrictive 2F exhaust manifold.
So if wiki is correct an 80' 2f is 7.8:1 compression and a 3FE is 8.0:1 compression. I haven't done the math but gut feel seems like a small amount of shaving on the head could bump the compression to the 8 territory.
So I've been reading through all the 2F, 3F, 3FE, 2FE threads in the archive however pretty much all of those threads were in the time before the proven TBI systems were in existence. So I'm wondering if I'm better off just working my 2F head a little and putting the sniper on. All my brackets stay the same and other than the sniper wiring nothing much changes on the truck. I can aquire the 3FE engine and wiring for less than the sniper unit but then its a fair bit of work to build up a 2FE and will be a bit of down time.
