are there any parts that arent compatible between the 5.0 and 351W blocks?
Thanks in advance.

Everything will bolt up including tranny.Your accessories should bolt up as well.

In fact if i remember correctly even the motor mounts are the same.

The spacing between the heads where the lower intake mounts is wider on a 351. You'll need a 351 lower intake.

and since the 351 is a taller block, you need a hole in the hood or a 2" cowl hood with additional clearance for the top of the engine.

what about the motor mounts?

Thats not true roundman.

Ive seen a stock 460 under a stock hood.

Motor mounts are the same.

I may end up with an extra 5.8L GT40 style lower intake... I've got two right now... project is underway.

I was referring to my 88 hatch. right now the right lower corner of the intake is just short of hitting the bottom of the hood. it did hit it some before I put the solid motor mounts in, cause it left a scuff mark on this corner of the intake, so I don't see how he could get a taller deck 351 under a stock 88 hood without cutting something for clearance or lowering the engine in the frame some.

Well theres an 86 capri here that has a 460 in it with stock hood and the whole 9 yards.

I too called bull ****ter until he popped the hood and then my jaw hit the floor.

Its been cut now to accomodate the tunnel ram and dual 450's but in stock "CARBED" form it fit.

I may be wrong about the EFI im not an EFI guru as most know.

We know Killer, that's why some of us are out here to keep you honest! LOL
I didn't say it couldn't be made to fit, I was trying to save that without any changes, it probably wouldn't fit without a cowl hood for clearance. Bottom line, it all depends on what car he's putting it in now don't it?
