heres the deal, just came across a great deal on a set of exploder heads and intake for 200$. so i was wondering what cam i should go with. i have a 125 dry shot on it and wanting the best all around cam. before anyone chimes in and says to get the heads ported before puttin them on, keep in mind money is tight. im leaning towards the tfs stage 1, but if you all think there might be a better one for my setup please let me know. also what size throttle body and injectors would work best. my car is an 86 so still has speed density but also found another deal on mass air setup if you all think it is a must. again, any feedback would be greatly appreciated.

simple, stock or the isky 252/257 cams...these have wide lobe centers that produce good vacuum. Most aftermarket cams do not work with speed density since you need to have a cam that produces at least 19 inches of vacuum. If you do not have enough vacuum, it will get stuck in "open loop" and the injectors will just dump raw fuel out of the pipes

whats your feelings on the mass air swap. i can get it all for 50 bucks. the whole fuel injection system, ie- wiring, computer, sensors, whole nine yards since the guy went to a carb. down time is no big deal being that it is not a daily driver. and i would like to get as much out of this setup as possible and have heard lots of good things about the tfs stage 1. and if i am going to have the heads off already i figured i might as well swap the cam. my apologies if i am being redundant. but like i said i'd like to get as much power as possible and i am not happy with the stock cam.

If you can to the mass air swap for that cheap, then go for it!! You'll want a bigger MAF though...stock sucks (55mm). Get a C&L 76mm or PMAS 75mm (was Pro-M). Depending on your plans for your car, 65mm (possibly 70) TB is all you'll need.

Also, you can do some easy port matching and smoothing yourself if you have a Dremel or similar tool. You will also want an aftermarket intake manifold (or an explorer) to get more air to your motor.
