318 build, my first engine build

Try not to do this:
Low compression, a big cam, stock TC, and 2.76 gears. It never works out in a streeter.

If it's in the budget, some closed chamber heads will really wake up your teener with those 167s. With 58cc heads, it is possible to make around 10.1 to 10.2 Scr. This will allow a cam with about a 62* ICA, to make a lotta teener punch.
Guess what cam has a 62*ICA, hyup the 268/276/110.
Normally, this cam is a bit on the big side for a teener, cuz normally guys screw it together with the wrong compression ratio. But at 10.1, you're all set.
Well, yur still gonna need; a 4-barrel system, headers and a hi-flo dual exhaust, a TC, and probably gears too,with a suregrip,a transmission,tires, brakes,a torque limiter, a V8K and Tbars,a HD cooling system,a distributor,a tach, a rev-limiter.............
Nice Duster!

The 268 cam is a little hard on gas. The next smaller cam is significantly better. If you get it in a SolidFT, you can keep about the same .050 or so, but you will have to fine-tune the Scr down a bit. This will drop about 7 or 8 degrees of overlap. The less overlap will be a lil less fussy about having headers.
Without the overlap and headers it will make a lil less power, but if the price of gas goes thru the roof in the coming years, it's something to think about. At this power level, it might only be 12hp, no big deal. Leave the spare tire at home and you'll never feel the difference.The smaller cam will make more low rpm torque than the stock 318, but will still want a bit more than the stock 1850 stall,perhaps 2400 and probably at least 3.23s..
