FE Technical Forum / Get a dial back light.

A dial back light will allow you to check your timing curve, this is very useful!

FE Technical Forum / Re: Flywheel weight theory? Street cars with less traction....
« on: May 11, 2011, 11:20:47 AM »
On a street car with less then ideal traction a heavier flywheel can be a good thing to help reduce wheel spin on launch allowing for a smoother acceleration.
Depends on the engine combination. As seen in Jays book, some intake/engine combos have a really steep torque rise, that combined with an advanced cam and a very light drive line could lead a Mustang straight into the ditch... making it not as drivable.

FE Technical Forum / Re: 390 - Tune up w/ stock parts.
« on: May 11, 2011, 11:06:43 AM »
As Jay noted, and i have done myself, a little time detailing 390 GT heads, Truck heads (D2T) or C6 heads can easily get you into the mid 350 HP range and with a LOT of torque as Jay noted. Also, some details you must remember to follow though on: zero deck the pistons, carefully work around the cylinder head bowls and chambers, re-curve the stock distributor for more initial advance (12 to 18*) and a total of 34* to 36* range, get stock adjustable rockers if you can, get your cam, crank and rod clearances right, use ARP rod bolts and re-size the big ends, consider lighter forged pistons, run an extra quart of oil in the pan to ensure it does not starve at high RPM on on acceleration, degree your camshaft so you know if your straight up or advanced and are NOT just guessing based on spec sheets... that only works about 30% of the time.
If your really want to go the next step, install a 4 speed TL or a TKO 600... that will make the power more fun IMHO.

FE Technical Forum / Re: Bore Notching

My machinist will do a little of this as a matter of practice, he will clearance the intake and exhaust area of the cylinder bore a touch, claims it helps the flow somewhat. No direct testing to prove it. We just finished a Boss 302 (342 CID) type engine with Cleveland heads, had to (or chose to) notch the cylinders for that as well. He does manage to build 600 + SBC and SBF's and other stout engines by the seat of the pants, so ill give him that.
He also un-shrouds the chamber to match the chamber work to help the swirl (if that is possible in the old wedge FE's, as they don't swirl too well... according to carbon tracks on the pistons and such.)
