@carnut92506, Naw, I dont know why you have to say that, Im a Ford guy, but the 440 aint no slouch, i wont Denny it, i think its a great motor.

@gregmacknass incorrect

with a holley stip dominator, an 850 holley double pumper, headers, and a lumpy cam, you can get 500 hp from a cleveland. Talk to dan jones, the expert on 351 clevelands.

By the way, the boss 351 1971 mustang sported a cleveland underrated at 383hp. (actual dynos report 400rwhp)

Stock 4v clevelands made around 330hp

You are thinking of the weezy 400 that used 2v cleveland heads.

I mean Temp on each cylinder..440 .30 over So actually 446 cubic inches-Forgot to mention Bigs Perf stage 5 750 Holley..440 source heads. 10:1 compression--92 octane. Ran on the Dyno at car show with 395 HP to ground.

I have a 440 in the car that I want to dyno tune..I have the Edlebrook street dominator intake manifold. With the K&N Xtreme air filter. I do not run without a air filter & it appears that you are monitoring O2 on each cylinder. Have you dyno tuned the motor in the car? placement of the 02 senser bung on the Header? difference in actual HP to the ground?

@halohadel Dude you are really making some foolish statements. I like and have owned 351 Clevelands but the 351 Cleveland is not going to make the same HP/TQ that a 440 is going to make if you throw similar mods on both,with the same compression and etc,etc,etc......its just a matter cubic fucking inches with the Cleveland bringing almost 100 less of them to the gun fight.

@carnut92506 I have to agree, Ford and GM guys think there muscle cars where the kings of the roads and tracks back in the 50's-70's but when you start showing them the facts, like fastest muscle cars where Mopar and mopar dominated the drag strip and that GM left racing in 64 and didnt come back until 70. And the fact Ford would only allow there sponsored racers drive there top muscle cars where as Mopar let anyone with money drive.They get all pussy hurt and act like you kicked em

[Boredout454]

@PlumCraZRT Yup thats exactly right, Im driving a Chevelle with a 468ci with 500 to the wheels (around 590-610hp at the crank) and its completely street friendly. My friends LS1 and his friends supercharged mustang cobra are putting around 490ish to the wheels and the cobra is always breaking down and the LS1 doesnt like the street to much.

[PlumCraZRT]

@halohadel LOL... your 351 is making 505 hp @ 6700 rpm with 2 inches of vacuum (no power brakes), a 4000 stall converter (no automatic on the freeway), with 350 ft-lbs of torque. Guess what, dude... you don't get power for free. Honestly, displacement is the only way to make more power and keep it street-friendly. It took me going from a 383 to a (500 hp) 451 to understand that. Open a book.

ford and GM v-8's are magnificent. i also have a 12 inch dick, attended MIT on scholarship, was former president of the dominican republic, and once dated lindsay lohan.

[midatlanticcycle]

one of the most beautifully designe V-8 engines ever manufactured. if you know the B/RB/Hemi engine design you'll know what i'm talking about.

[carnut92506]

Mopar is the king of Big Blocks. Once you state how much power and torque they make...the Ford guys are so intimidated that they always have to pull some lies out of their ass.
