While it doesn't have the lift of the more modern grinds from Lunati and Comp, it's ground on a much better LSA for a 350, especially with the smaller valves. For a Jeep mill that is not likely to exceed 5500 rpm, just use 350 pistons and the short 400 rods-a combo that will actually give more low end torque than using the longer aftermarket rods.įor what you're looking for it to do, I'd choose the Isky 270-Mega If you really want something that has low end power and that can handle a bit more cam, you should build a 383. 050, and even then I would be using a set of Rhoads lifters (they work as advertised) to enhance the bottom end. If you want something that works, I suggest something in the 218-230 range at. The idle sound of a cam is not something that I would even consider selecting a cam-seems pretty vain. If you want to just build a hotrod, perhaps you should forget using a Jeep as the base vehicle. If you do manage to tune that carb so that it actually runs, it will likely be on the rich side (poor mileage) and it will be very sensitive to altitude changes because of the poor vacuum response. A 750 Holley is completely ridicoulous on a 350, even on the 70-72 LT-1 versions that could turn some healthy rpms (big heads/cam and 11:1), and that engine isn't worth crap in a Jeep (I tried one in my youth). The Q-Jet is really unmatched on a combo like that IF you can find someone who knows, REALLY knows, how to build and tune one.Īll above is good advise. I've personally built one for my brother with a stock bottom end, stock heads (freshened), Performer intake, HEI, and headers and Q-Jet. You can hear it a bit, and it'll run good without a converter. Get some better heads, raise the compression.Īnother Comp cam I've loved for years in your type of small block is the 268H. If you really want a rumpity rump cam, build the rest of the engine to compliment the cam you listed. Yeah, they won't hit at idle, but it'll run so much better you won't care. Were I you, I'd back down about two cam sizes in the Xtreme 4x4 line. The flip side is, if you have a stall, then 'low end' becomes a bit higher. That's not to say a hot cam will kill power so much that it won't have enough to pull your **** out of your pants, as my Dad used to say, but a simple rule of thumb is, if it calls for a stall, the low end is lacking.

The more 'rumpity-rump' of a sound it makes, the less power it makes down low.

Rough idle and low end torque are mutually exclusive.
