That's a Windsor block and he needs a Cleveland. I don't really know the difference with the block. The M-6010 series of BOSS blocks are readily available as accepted replacements. I have the BOSS 302 block in my Mustang.

That is correct Dale, the Cleveland blocks that are nhra approved will be available in a few months. When they are cast and machined they will be added to the accepted products list

The Windsor engines were built from 1961to 2000 and the Cleveland family from 1970 to 1982. Both families had 351 cid engines. 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.

about .300'' taller deck and .250'' larger main aren't direction you want to go on stock/super stock besides being illegal,if building 427 windsor, then taller deck and larger main works well.

The current Windsor Boss 351 blocks are available in both 9.2" and 9.5" decks. They also have the Cleveland main size.

They even have a 9.200 dh with 302 mains.. They are harder to find but available... Talked to the guys at ford the other day..

In the early 90,s when we ran the 351 C in GT/B we had a lot of issues when they really started making power. We went 9.30 at almost 148+ in 1994 with this combo with a G force trans that had to be clutched on all shifts.. So they will make a lot of hp..

I had an entire kit with all the part numbers and all for ford to approve, a Windsor block for the Cleveland then and ford never submitted it to NHRA. I already had NHRA ok with it if Ford had submitted it as a replacement.

I thought we were talking about using production windsor in place of Cleveland,sorry.

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...
