I have a similar situation with my 53 3100. The 292 I think is about 3" longer than the 235. My primary radiator is almost 7" thick with the 3300 CFM electric fan. After my crank snout I have 7 3/4". That is my custom SFI damper with serpentine pulley, crank trigger, 3" blower pulley and 1" oil pump pulley. Because of the leverage on the crank I am running a big block timing cover seal. I have a Crower billet crank. I also have to deal with the 6 intakes on drivers side and 6 headers on passenger side that will be in the firewall. Iv'e done a lot of measuring And I think I can get the radiator forward about 6". I'm looking at moving the engine back about 8". I may move the pedals over a little. I have a Tremec TKO 600 trans and ordered it with the mid shift kit. This puts my shifter about 3" in front of the seat. A dog leg shifter and I should be fine. Might have to get a little creative under the dash but probably not. good news is it's skinney. I like the idea of weight being moved to the rear. NHRA does not permit the moving of the engine rearward for weight distribution but does allow it for fitment. My point of view is get it where you can and make the truck fit around it. Thank you for our time.
