Ok You have to buy cleveland type pistons because of the canted valve heads, thats what makes it a clevor.
They make kits to do just what you want to with the 351W now.
The block has to be threaded to accept bigger head bolts and there are alot of
other little tricks you need to know about.
Back in the 80's we called them Mexican Style Boss's but it's really the same thing.
The only one that made a intake for them back then was Yates racing.
Today there are lots of companies making kits to do the same thing.
You want to talk to Dave Severson on here, He was talking to me awhile back about
a new head that they make now to replace the 2V and the 4V heads.
It take the best things about both the heads and combines them with alot better flow.
Another guy you may want to look up is Rick DeVitto and his 65 Ranchero.
He is not on here but is a friend of mine and is running a 408 Clevor in his Ranchero.
Just type his name and his car in and it will pop up if you Google it.
He will be able to answer most if not all your question about a clevor motor.
Hope this Helps, Kurt

Trick Flow makes the head, it's a 225 runner and looks like a really nice head. Best of both the 2V and 4V Cleveland heads....

Did you think about just using the 400 engine???? Its a Cleveland

[vara4]

The 400 is considerd a big block though and with the taller decks there maybe some clearance issue's with the 63 if you still have shock towers.
You will probably have the same issue's with the 351W as well though. Also if you go with the 400 you'll have to go with a big block trany or adapter plate
to run a small block trany. Rick Devitto is running an adapter plate with a GM trany and has had very good luck with it, behind his 408W.
The 351 Clevelands and the Windsor motor's are all small blocks, If you get into the 351M or 400M those are big blocks and have taller decks on them.

im useing a 74 351w i will not have shock towers nomore they are removed because of the gasser frontend.i have all the room i want now i can even fit a 428 if i wanted but i dont want that. i seen the 3v heads on the summit sight im going to run 70 351c 2v heads i want that old cast iron head.

then save yourself a lot of grief and simply build a 351 cleveland 2 barrell engine .. you can get a 4 barrell intake for the two barrell engines ..

im not building 351 cleveland i see cleveland at ever car show or event the clevor u never see them anymore

[jerry clayton]

I think you have things a little mixed up
