SBF = Small Block Ford, ie pushrod 289 or 302
Supercoupe = 1989-1995 Thunderbird Supercoupe. Came with a 3.8-liter supercharged V6. 89-93 models had 210 hp and 310 lb-ft. 94-95s had 230 hp and 330 lb-ft.
I have to ask: If 600 rwhp is your goal, why are you even considering rebuilding the 4.2?
Any 4.6 or 5.4 mod motor will fit in your truck, but will require a new transmission/wiring harness, and will be a lot more work.

Definitely staying away from rewiring the whole truck so I guess block rebuild is the option I'm going for.

also doing the whole cam swap again and porting the heads etc
Also one thing to point out is that the block is made out of cast iron most blocks nowadays use aluminium which is much weaker. That's one of the benefits of these older trucks they were built out of solid metal parts even in the body not like plastic & cheap aluminum nowadays

Not true with a bigger crankshaft, coated bearings, anodized pistons, stronger head gaskets, hardened main & rod bearings, custom cnc'd seal etc its more than possible

Not laughable you're just one of those people that think everything has to have a V8 in it to make serious power. Which has been proven wrong multiple times.
I came on here to get some insight on options and Will94SC provided it.
