335 series questions
I have two questions for you guys. The first one is about a 351C, is it safe to have them sleeved? I have a friend who races dirt track and cracked a cylinder and he will not run a sleeved block(he purchaed a new world block to replace it) and was going to give it away for scrap, the entire short block minus his roller cam and lifters. I would like your opinions on this because i would like to build a mud racing engine for my bronco if this block will be ok with a sleeve in it.
And the second question is what engines can i use replacement 5.0 roller lifters in and what do i have to do to use them(if any), and what kind of cam do i need to run these lifters? If any of you can help me with these questions I would be greatful, thanks, Dave
Oh yeah, one more thing, after searching and reading this forum I guess I can use 351m & 400 heads on this Cleveland block? I just want to make sure.(dont be mad if i'm repeating a question i have been reading enough on here these past few weeks to make my eyes bleed)

I can't answer your question about using a sleeved block, but you should be able to find a rebuildable block for a reasonable price.
You can use 5.0 roller lifters if you have a specially ground cam with a reduced circle. Comp Cams makes retro-fit roller cams like that.
You can use 351M/400 heads on a 351C block. Be sure to take out the thermactor bump in the exhaust port. You can also use Aussie heads.

yes you can sleeve a block I have seen race blocks with 3 and 4 sleeves in them, and I read an article somewhere (can't find it right now) where the prostock racers in the 70s such as Bob Glidden were sleeving all 8 cyl on a cleve block. And if you check this last years engine masters challenge look at Kaase's 408 cleveland as I recall he had sleeved all 8 cyl on it and made over 600hp (I know he did it on hte 460 he won with the year before) so I wouldn't be afraid of sleeving that block at all but it does seem to cost right around $100/cyl

hey guys, thanks for the replies, as soon as I read them I called my friend and told him to hold on to the block, I knew that deisel engines are sleeved and that they have high cylinder pressues but i wasnt sure how they would hold up in a gas engine during high rpm operation The CLeveland i'm getting is only cracked in one cylinder that we know of but ill have it extensively checked the machine shop and may get all of them sleeved and take it back to stock bore and start over. So thanks again guys for the information, Dave

Jon Kaase just won the engine masters with a completely sleeved Cleveland block. fortunately/unfortunately the sleeves are stronger than the original cylinders are/were. as long as the work is done right a sleeve should be no problem.
