Who is the smartest Engine Guy in here?
 

Ok so I just went and bought a block from the wreckers, had awesome compression and oil pressure the dudes said it came out of a 85 F-150.....I was told from various people that I can use any block from 79 onwards as they have all have roller cams as well as everything is the same..............WRONG ...............Unless I got a dud!

1)First, I do not have a caliper so I just measured with a tape measure the bore of this engine, and the bore of the my other engine, my orrginal block had just under a 4.0 in bore and this one has a 3'7/8 ths inch bore.

2) This is a flat tappet stye block, and cam.

I can get the engine block numbers, and well my question is this actually a 79 & up 5.0? As well can I make it work?

You won't be able to measure the bore with a tape measure. Also, sometimes you get a ridge just above the top ring in the cylinder bore. The only factory 351w roller capable blocks are the 94-96 or the SVO blocks. The earlier ones can use roller cams but, have to have either a reduced base circle camshaft or a specil lifter (tie bar lifters).

Well I took my old pistons, and there is no chance in fitting them inside this block when the other block fits in easy..... Its clearly smaller! So if I want to run my 5.0 HO cam in it what do I have to do? As well what about this bore difference?

^^^^ Sorry that last one was confussing, I took my H.O pistons and tried to fit them in this wrecker block, and they have no chance in fitting, when they can easily fit in my h.0 block

just bore the cylinders and stick a .600 lift cam in it ;)

So is it a 351 or a 302?

RE: Who is the smartest Engine Guy in here?
 

NO IDEA! hahahah the bore is a 3" 7/8th rather than the 302 4 Inch bore so anyone have any idea what ford engines have this bore?
