I'm helping my brother pick out parts for his 66 Mustang. Car will be 60/40 street-strip. I'll be doing the engine and trans build myself.

Parts so far:
68 302, .030 over, stock bottom end with cast rebuild type pistons. Bores look excellent and crank is std/std w no marks or scuffs. Prob doesn't have many miles at all since a basic rebuild. No ridge in the cylinders.

Performer RPM intake, bought a couple of months ago.
Tri-Y headers, came with the car.
Holley 600, came with car. I just rebuilt it.
Pertronix ignition inside stock dist.

Just purchased and delivered today:
Twisted Wedge aluminum heads. Will port match to intake, but otherwise leave alone.
Comp Cams 270S (.528/.528, 238/238 @ .050)
Aluminum roller rockers.

To purchase: basic rebuild kit with TRW forged flat tops, .030 over. I am sure that the bores only need a light hone for the new rings to seat. No need to be bored. I wanted to leave the cast pistons for now, but he says he might want to spray a little in the future, so forged it will be.
ARP bolts for the stock rods.
std volume oil pump
double roller timing chain.

Trans is a '71 case fill large bell C-4. I will freshen and add a shift kit. Also will get a 10" converter 2500-2800 stall range. Rear is an 8" and the gears will be changed to the 3.50-3.70 range.

Anyone see any glaring errors or problems?

Thanks,
David Cole

Looks like a nice street/strip combination. The only error that i see is the cam specs that you gave are for a 282S and not 270S. The 282S will pull hard to about 6200-6400 and the 270S will make top HP at around 5800-6000. 282S has a rougher idle and may like more compression than the TFS alum. heads will give. Holley 600 will work but a 650DP is better. Those heads will flow!!

What bluestreak said,

Plus the "why try" headers have go to go.
Back the exhaust up with some Borlas or equivalent free flowing exhaust and it should be good to go.

Carb is too small for those heads with that 282S cam.
Better off with a 270 if you want to keep the small carb.

Dave,

Maybe not glaring errors or problems, but to consider:

-- You didn't mention whether or not you'll have a traction-loc or locker in the 8" rear... I hope you're not planning on running an open differential...?

-- maybe you can sell the Tri-Y's and get some long-tubes headers......?

-- At least 2.5" exhaust with an H-pipe....?

-- Any traction bars......?

-- battery to the trunk...?

-- clutch or electric fan....?

-- water pump, altenator & crank pulleys?

-- dropping the pwr steering, pwr brakes, A/C?

-- tall rocker covers?

He's right.

With the TF/TW heads, you could get alot more out of that 302 with a diffetnt combo.

I almost forgot!

Unless you got some special piston or somthing, the "TRW forged flat tops, .030 over" won't work with The "Twisted Wedge" heads. In the design of these heads, thay moved the location of the intake valve. You're going to have about .015" piston to valve clearnce, if that.

You can eather have you're pistons "fly-cut"
or TF sells pistons with a nice streetable 10.2:1 compression ratio.

I don't want to see you build a grenade here. Even though the cylnder walls look good, have somone check them with a dial bore gauge. Make shure you balance the pistons, crank and rods! And be shure to check the piston to valve clearnce!!

I also would at leat run an Air Gap or Stelth.

Thanks guys.

The headers will go as funds allow, budget is almost gone. They came with the car, so we'll have to use them for now. It does have a 2.5" system with an H pipe.

The cam is the 270S.

We would liked to have done the manual swap. Already had a T-5, but the budget wasn't there for a conversion. I can build the C-4 for cheap and the converter will be a 10" that belongs to a buddy. It will be freshened and the stall adjusted.

I will check the P/V clearance and all the normal stuff just as I always do. Wasn't aware of an issue with the pistons. I know the TW's have relocated valves, but Trick Flow says they will clear as long as the cam is under .540 lift and has less than 290 adv duration.

Later,
David Cole

The TFS heads, 270S, and the 10" stall conv. should make for a nice little tire destroyer!

You shouldn't have any problems with valve clearance once you add the lash settings.
