They also will be available with optional 302 mains, all bulkheads on all blocks are solid (XE design) all blocks have a provision (material added) for a left hand GM starter (drivers side) all blocks have enough material to bore the cam tunnel to 60mm and, as of now the patterns will be updated for offset or non standard lifter bore locations.

Non standard deck heights will be added at a later date.

The Cleveland got the good cylinder heads and the Windsor got the stronger block. Some folks have reworked the water passages to fit Cleveland heads on Windsor blocks but NHRA says NO! That's why these guys are so interested in opening their wallets for aftermarket approved 351C blocks.

The currently available Ford Racing BOSS 351 is a Windsor. You could run it in SuperStock but not Stock.

OK, I gotta ask...as far as I know the Cleveland stopped production in 74 and after that it was the 351 modified which is WAY taller than a C and has longer rods etc.(same block as a 400) I looked up a 77 351M in the guide and as replacement rods it has 351C rod, 5.78" made by crower??
Now, look up 77 400 and it shows rod length as 6.58". The 351M and 400 both have 6.58" rods and the 351C has 5.78" rods. So, either the guide is messed up or 351C have been produced from 70-82 but I've never seen a 75-82 351C for some reason??

Who has ever seen a short deck height 351C, the same as a 70-74 351C in anything newer than a 75 car??

EDIT: Oh, and firesale, you're correct on the poor oiling system, only cure was to block off the passages to the cam and oil it externally from the sending unit "T" down to the cam from up top. Took the bottom end out of countless amount of clevelands until another ford guy showed me the trick.

For once, the guide is correct on the rod lengths. The 351M had a de-stroked crank and pistons with a taller compression height to bring the cid down to 351. It was built until 1982 and was Ford's last pushrod production engine.

According to the guide the 1970 BOSS 302 had 5.090 rods, Same as the regular 302. It's not perfect.

This is Bill's build thread. I'm going to leave it to him as the owner. I'm talking too much...
