i have a buddy that has a 87 4x4 with a 306 with one of those cams it really hits hard and performs even harder it has 3.55 gears and 32 11.5 mud tires and followed my 99 f250 powerstroke with 35 12.5s and 4.10 gears! That was my reasoning behind the alpha-cam

A 351 makes more low rpm torque than a 302, so as long as you have something a little better than the stock cam you'll out roost you bud every time. Either of the motors you have are good candidates for a truck, put the Comp Cams 35-255-5 flat tappet cam in the '87, or the 35-349-8 roller cam in the '94, strap on some headers and a decent exhaust and let the mud fly. Both of these will run on a stock 351 computer, no problems.

I hope to use a Holley 750 double pumper carb that i bought to put on a 400 chevy back when i was still in high school. Thanks for the part numbers too im not really interested in out bogging my bud with the 302 just the guys that say only a chevy can go down certain trails and my dads old ragely dodge that performs real well too considering that its a dodge.
I almost forgot I designed and built my own mufflers for my 2004 f150 they have a full flow like a race muffler but they also have a mellow tone with the cats still intact. i have some more designs that i hope to try out one the 87 4x4 that im working on still have got the 300 six out yet it will be a few weeks before i do that because of the long work hours of my profession.(I am an Industrial Maintenance Mechanic or Millwright)

If I use that compcams roller do i neet to change anything with the heads as far as the valve springs or will the factory one work. I plan on doing a light port and polish on the heads and intake definatly going with headers and a carb so i wont have to worry with any computers or anything like that.

For a rolller cam upgrade, a better set of valve springs will be needed.
There are a few off the shelf cams that will work well, but the best cam for your combo will most likely be a custom grind...a little more $$ but it takes the guess work out of choosing one that is right for your combo.

Here's an example that's not a real good comparison...
I have a 357 Cleavor motor runnig 11.7: 1 comp and a big cam. It sports an 800 DP an can get with the program. I had just finished rebuilding a .060 400 for my '78 Bronco w/ a good port job, big valves(like it really needed them) and a decent cam, and decided to put the 800 on there to get it fired up since the 750 V/S was used and unknown to me. It fired up and ran in it enough for breakin. I switch to the 750 and ran for a long time with good results. On a whim, I decided to try the 800 after having the 400 dialed in....it just would not take that 800 no matter what, too much carb. In fact for normal street driving I eventually used a 600 V/S with great results, but it didn't have that top end like the 750. The 600 edel is also a good choice due to the big differance in size from the front to rear throat bores.
Not sure what you intend to use this motor for, but unless you have a HUGE cam and are planning to run very high RPM, you'll be dissapointed with the 750 DP....
