J-Madd Posted April 23, 2017 Author Report Share Posted April 23, 2017 I put that 421 on a stock frame after being for sale for ages and it fired right up and runs like a top. My only problem was that the front end won't stay down. The 392 should be the same. Fire it up to knock the cobwebs out and run the shit out of it. I'll probably put it in a chassis soon just to play around on. Tired of such a good motor setting on the shelf.

gusto Posted April 23, 2017 Report Share Posted April 23, 2017 What's the HP difference between the two? And when you build a 392 did you reinforce the stock crank or buy aftermarket? Quote Link to comment Share on other sites More sharing options...
J-Madd Posted April 23, 2017 Author Report Share Posted April 23, 2017 The HP is about the same. The 421 has a tad more TQ. The crank is a trued and welded OEM. Sent from my STV100-1 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
