351 Cleveland
ok guys, looking for some personal prefrences and/or experience in building/modifying a Cleveland, starting point complete running motor...
she is to be rebuilt but just what to do... I don't know... she will never tow or carry a load again, is in a shortbed F100 2wd with a C6 and 9inch, all advice welcome, I want her to absolutley launch of the line, but also need a highway cruiser, looking for ideas on build options for this combination and also any advice for strengthening the trans, etc, that may be needed as a result...
thanks guys...

Well here's what we did. Bored 30 over with forged flattops, balanced rotating assembly, used a Crane adjustable rocker arm kit, installed a 40% underdrive pulley set, used a cam that raised the lift without raising the duration. We also installed a oil line from the old pressure sending unit to a fitting on the rear of the block to oil the back of the crank better. We also slightly enlarged the return holes in the top of the block to help oil return. A roller fulcrum kit is available but I don't know if it will work with the rocker arm kit. We had 2bbl heads but be sure your heads and deck are flat. The choice of carbs is yours but we used an old 4100 Autolite and reworked the secondarys. The standard vacuum system dogged so we engineered a way that allowed the vacuum to partially open the secondarys then a mechanically alteration took over and kept the hesitation out. This motor was built origonly for a dort track car but it also ran like a raped ape when we put it in a street car. We figured it was 357 cubes and 360 horse. An h-tube between the exhaust pipes also is worth about 10-15 horse. You need back pressure so full pipes will help. If I remeber more I'll post it here.

What heads are on it? The 2V heads will give you better low-end TQ than 4V heads, especially the quench/closed chamber 4V heads.
The C6, if built correctly, is bulletproof. Same with the 9" rear.
Since you want torque, don't go too big with the cam lift/duration. I prefer Comp Cams based on great experience with their products. Call them for recommendations based on what you want, they know their products best!
Consider a dual-plane intake with a 600-700 cfm carb. Vacuum secondaries would probably be best for your application and the results you want.
Clevelands need the exhaust to breathe well, the intake ports are already fine stock. Definitely put headers on it for torque, I like Hooker, just my preference.
Enjoy!
