The Cleveland is at least 300lbs heavier.

You should come over to the dark side and feel the noise 😎

Why? Much taller deck height? Are we talking about the same size engines (cubic inch wise)?

Ho lee fawk we need a sarcasm emoji, lol. 🤣😆
I was joking because everyone says the Cleveland is so much heavier than the 351w, all because of the timing chain cover being cast into the Cleveland block, maybe an extra 5 lbs 🤷‍♂️🤦‍♂️
No the 351 Cleveland is 9.2, 351w is 9.5 deck
T meyer shows engine weights on his site. Cleveland with aluminum heads and intake is just over 400 lbs
 
The following numbers come from an early Ford catalog and are for
"typical" engines. The dimensions include such things as air cleaners, oil
filters, water pump fan, etc., but not bellhousings.

Engine - Width Length Height Weight

289-302W - 24.0 29.0 27.5 460
302 Boss - 24.5 29.0 28.5 500
351W - 25.0 29.0 29.0 525
351C - 25.5 29.0 29.0 550
351M-400 - 26.0 29.0 29.0 575

Omg, I was joking 🤦‍♂️
However, I don't think a 351c is 25lbs heavier than a 351w. And how can the 400 with a 10.29 deck only be 0.5" wider than the 9.2 deck, lol, and the same height 🤔😆
 
Don't let him confuse you Mike, the windsor has a 9.48" deck also. Really fucks people up, especially those Chevy builders when they skip checking ptv clearance and verifying compression
 
Just an fyi, when I went from my lean 850 aed to the 1050 dom I lost power. That being said my old street edelbrock 750 was down almost 40hp compared to the 850

Every dyno I've watched the carb size hasn't changed hp numbers enough to matter in my rpm range.

Ive checked every cfm calculator, 427ci at 6500 max rpm is 750 street, 950 race. Even less at 6200rpm

That's exactly the plan when I track it. On the hunt for a 950 brawler, just need to make sure she doesn't blow on the dyno first

That edelbrock is basically a carter, nice tunable street carb but....

I honestly know nothing about Fords, well except that for some stupid reason they only have four bolts per cylinder and you have to remove the heads to change the lifters. That is kinda dumb...........

I know my aftermarket blocks (SBC) are a full 40 pounds heavier than the stock GM block. Same identical dimensions. Amazing the difference in the metal used and cylinder wall thickness.

Only have to remove heads on a 302 to get the lifters out. Not on a 351. Putting the distributor in the back is kind of dumb too. 😂

Ffs, no you do not have to remove the heads, that's 8.2 stuff 🤦‍♂️🤷‍♂️🤣.
4 big bolts or 5 tiny ones, LS seemed to think it was ok 😆😉
Yepper, my xe block is 15-20 lbs heavier than a stock one and the Arrow Cleveland block is that much heavier again. Thick walls but also solid oil pan rails and main webs, thicker deck, hi nod iron 😀
Hey, have a look 351 mains compared to sbc. Do aftermarket sbc blocks use the same size bolts as oem ?
 
The replacement locks just arrived. I'm pretty sure I didn't deform the first ones when removing them. Looks like they're just dog shit quality.20250712_164620.jpg
 
They are probably stamped-steel. I only use machined steel. Just got all my valve train stuff from PAC, took a week.
