Cam Choices
OK, I am soon to be getting a 94 Gmc Short wide truck that originally has a 4.3l V6 engine in it, I am also getting a used 4 bolt main 350 engine from a friend for free, so I am going to build the V8 in advance for when I decide to do the swap, the truck is TBI right now, but I plan to just use the stock electric fuel pump an run a return style regulator, probably a mallory, and carburate the engine so I wont have to deal with the electronics of a tbi, my question is to what cam I should use, I will drive the truck to and from work mainly but I still want it to have lots of power if I decide to hit the gas, or maybe take it to the track every once in a while to show the punks in town that it does have power to go along with the sound.
The engine I ill be getting is a 4 bolt main 350 from a 88 suburban, I will be using a brand new cast crank (don't see the use for a forged one unless I build a massive motor) and the stock rods, (may decide to upgrade to a set of eagles) with a set of ported, polished, and gasket matched 993 casting heads with the stock 1.94 and 1.5 valves, the heads will have a 5 angle valve job and aftermarket valves and springs, I will also be running flat top forged power pistons because the heads are 76 cc's, the heads will be flat milled an additional .020 thousandths for a little more compression, I will also be ordering a performer rpm or a torker II intake with an edelbrock thunder series carb, (or what ever intake you reccommend) the exhaust will be a set of equal length hedman headers with a set of flowmasters or dynamax mufflers dumped befpre the axle, and a 373 posi rear and an overdrive tranny, the camshafts I have decided to pick from are,
1. Lunati Voodoo Camshaft part #LUN-60103, 268-276 duration, .489-.504 lift, 110 lsa, 1800 to 6200 rpm's
2. Comp Cams Magnum Cam part #CCA-12-326-4, 286-286 duration, .490-.490 lift, 110 lsa, 2200 to 6200 rpm's
3. Lunati Street Master with 285-285 duration, .507-.507 lift (but on a 108 lsa)
4. Comp Cams XE part #CCA-12-246-3, 274-286 duration, .487-.490 lift on a 110 lsa.
Which camshaft would you recommend, I want the one that will make the most low end torque and use a low stall, don't want to have to run a stall above 2600 rpms, also what intake would you go with it, and how much stall do you think I will need for the cam?? I personally like the voodoo camshaft and the street master cam, but not sure about the 108 lsa, never had a cam with a 108 lsa.
Do yoe think my enine will make decent power and torque or would you reccommend I take another route?
Thanks for your help
Ditto on the model kits! My best were lost when the Hobby Shop burned under suspicious circumstances....
How did you get hooked on cars?
