4 bolt main windsor block

[65ShelbyClone]

That clears things up a bit. I alo heard of a guy on the Corral(?) that split(or at least cracked) a roller 351W, but that was twin turbo and around 650rwhp if I recall. Still alot tougher than a 302 by a fair shot.

So what would be the expert opinions for a twin turbo'd motor? I was thinking of a 427 or 347. What's the feasibility of doing something like that? The uses would probably be street/cruises/strip on occassion.

Either a 347 or 427 are both very feasible, but it would also be easy to overpower either block.....especially with a stroker. You can build a 347 strong enough to break a factory block without a power adder. Same for a 408 or 427W. It depends on what your power goals are. If you keep the boost down, then a srock block would probably last. If you want 500hp+ out of a smallblock or 600+ out of a 351W, then start looking at R302s, Dart, and World blocks.

I'm thinking about a turbo Merlin 427 in my 2+2...just a few horses in the pony!

Eh, hate to break this to you, but a "Merlin" is a Chevy block made by World....not a Ford design.

I think he meant Man O' War.

The "Merlin" he's speaking of was made by Rolls Royce and used in Spitfire/Mustang fighters and various other WWII aircraft. Made about 2,000hp from 16 cylinders.

Hey now that would be an interesting mod.

Edbert, i'm pretty he sure he was talking about the world products "Man O' War" block. world products also has big block chevy based parts called the "merlin" series, they have block, heads and intakes in the merlin series.

the boss 302 was the only production windsor block that had 4 bolt mains. you can install 4 bolt mains on the middle three mains on a 351w as there is enough material in the webs to allow for that. milodon has a four bolt main conversion for the 351w blocks.

Can I jump in here on this thread!?

Im trying to figure out my engine type, I got 4 bolts on the valve covers!
