Hello everyone, I am currently in the process of rebuilding a pair of 390FE's and wanted to get opinions from others on the build and maybe some info I didn't have. I have two motors that I'm building one is 0.060 Overbore and the other is STD. I found and purchased a third for super cheap to take the internals (under $100 bucks). The interesting part is that this third motor was a 390PI block including a C4AE-B Crankshaft and a mechanical cam with solid lifters (No pushrods sadly). I also found a practically brand new TRW 1-TM572 camshaft in a parts lot which is noted to be a non-cobra jet replacement cam for the 428 (mild cam).

I also have 4 cranks - 360 2T that came with the STD motor / 390 2U I got free in a parts lot / 390PI C4AE-B crank from purchased third motor / and a 428 1UB that I bought a while back.

I planned on using the 428 crank with the 0.060 motor and the 390PI crank with the STD. my main question is should I make a 410PI using the mechanical cam/lifters with the 428 crank or should I just go with a regular 410 using the TRW camshaft and use the other one to basically remake a fresh 390PI motor. I don't really know if there would be a crazy boost in performance I was just pretty interested to see what that motor would sound like and what power it could possibly put out.

Any help/suggestions would be nice. Thanks everyone!!

No solid lifters. Sell the cams to someone

Go with a roller cam and pick out what you want.

Flat tappet cams and lifters are unreliable these days due to materials and oils not being what they should be.

 

I see, Sadly where I'm at now I cannot really turn back unless I want to wait a while for things to sell and new parts to come in. I recently got the pushrods needed for the mechanical as I already had a pair of hydraulic. At this point the 0.060 motor is ready to be bolted on and turned, just trying to figure out which road of the two that I have in front of me that I should go down.
