[QUOTE="swampratt, post: 3302137, member: 15054"] I have had the 351 clevelands and windsors and I will say the windsors needed some compression and the heads did not move air well at all. Even installed 351W heads onto a 305.. it was a putz because of the loss of compression. I have also had the 351M and 400M engines..The 400 in hands down much more powerful out of the hole. I have had the 460 also and it was thirsty but ridiculous out of the hole. I settled on 455 Oldsmobiles in the trucks for best MPG and TQ. Usually pull 15 MPG and more TQ than you need for sure. If it is just a work truck I say 383 stroker old school chevy. Good MPG and 100,000 miles easy and plenty of fun factor. If it is a Trailer puller go more cubes. 400+ cubes for heavy pulling loads. A Bayliner Capri is not a heavy load. A trailer full of shingles stacked 4 feet high and 16 feet long is a heavy load. I reach for 450+ cubes if you do that daily. [/QUOTE]
