I stuffed the 351C from my 1972 Ford LTD into a 1971 Mercury Comet GT, essentially the same car as the Ford Maverick. It required a 12-piece set of headers in which the rearmost two pipes on each side ran across to the other side of the engine and exited through the exhaust pipe on the opposite side...sort of like a set of "bundle of snakes" headers on a GT40. I used a Crane Fireball cam with specs similar to yours, but used a set of Rhoads "bleed-down" hydraulic lifters (at low RPM's the lifters didn't fill completely with
oil, thereby reducing not only the effective lift, but also the effective duration) to give the engine good low-end torque, so mine grunted very well from an idle and once the engine was up to 2,000 RPM the lifters were fully pumped up, so the top end was great, too. Yeah, I surprised a lot of guys with that Comet GT, too.....until some dopehead ran into it on BOTH front fenders as it sat in the lot at a body shop waiting for the doors to be reskinned and the car to be painted...that was the end of that one

Jaydee, are you sure it was a 351C? The reason I ask is that the last of the Clevelands was the Q-code "HO" engine and that was discontinued with the 74 model. That engine was a disaster, the large valves and ports of the 351C-4V with an incredibly low compression ratio and open-chamber heads. I drove a 74 Torino with one and it was a REAL PIG, my 351C-2V would have been in the traps before that car ever made the 1/8 mile mark. It had no low-end torque and took FOREVER to accelerate to 60...I bet 10 seconds. What you had in your 78 might have been a 351M...one of the 335 series of Ford engines, but a bit wider (it had a higher deck, and used the bellhousing pattern from the 429-460 Ford/385 series engines. There was a 400M, too. At the time I was driving the big Ford, they were considered to be useful for little more than boat motors, but recently they have been kicking some serious arse in the Popular Hot Rod Engine Masters series....glad to see them getting the respect they deserved. They were large, heavy, and much WIDER than the 351C, though....most 351C engines will fit into most Cobra replicas, the 351M/400m engines, not so much. Here's the Wikipedia info on the 335 engine line:
Ford 335 engine - Wikipedia, the free encyclopedia
I still have a Cleveland block and two cranks sitting in my garage, along with 4 of the open-chambered 2V heads (which will NEVER get used with the current crop of closed chambered heads available).
Jamie, you mentioned the Cleveland was stroked....do you know what the eventual displacement would have been? I mentioned the two common stroker kits, but an overbore could have added a few CID, too.
Now, my dream engine would be a 427CID Windsor block with Cleveland heads...the "Clevor" combination. For some reason nobody that I know of has managed to stroke the Cleveland to 427CID, that "magic" number. The Windsor, though, has been done many times at 427CID.....and the Windsor engine has the priority
oil delivery system that keeps the mains alive at high RPM's, the oiling system was always the Cleveland's "Achilles Heel".
Cheers, guys!
