1974 Trans Am. 4010 lbs with me and 1/2 a tank of gas.
- Original 400 ci. Stock crank, rods, pistons... Was rebuilt in 1988 to stock spec.s. - Completely stock 4x heads with the exception of some Crane RV cam from 1988. Not ported. - Edelbrock Performer intake with out of the box Holley 650DP. Original intake and carb were long gone when I got it. - Hedman 3 tube headers with Flowmaster 2.5" exhaust, H-pipe with original style Flowmaster crossflow muffler. - K&N air filter in the Shaker scoop. Opened flap. - Stock GM HEI with Mallory coil, cap, module and Accel wires. Originally came with unitized Ignition, but was long gone when I got it. - Original TH400 trans with Shift kit. Rebuilt in 1990. Stock converter. - original 10 bolt rear end with 3.42:1 gears. - 225/70-15 BFGs on stock Honeycombs. - Koni Red shocks, stock rear leaf springs with no traction aids. Front stock replacement springs, stock sway bars with poly bushings. - This is as basic a combination as can be. It has been dead reliable for the past 17 years I've owned it. Drive 75 miles to the track, race, and drive home. Best E.T. to date: 14.19 @ 97.42, with crappy 2.1 60' times leaving at idle. Car has more in it, but I can't tune a carb to save my life

467ci 635hp
467cid Specs, my sig lists the track times and on the dyno we made 635hp@6400 and 575ft/lbs@4900. This dyno has proven to be conservative by about 50hp when track times & race weight are calculated. I drove this all over the place on the street and made well over 350 passes at the track before I pulled the motor to check everything over.

EFI 455 Street and Strip
1967 Pontiac Tempest 2 Dr. HT ...originally an OHC-6 1barrel w/ 3 on the tree.
This car was designed and built to be a REAL street and strip car. As such, it is by definition, a compromise. It is not another of the all too numerous “race cars with a license plate” that pretend to be called a “street car” while screaming down the highway at 4000 RPM, sucking fuel like a Titan rocket! Seriously, what kind of gas mileage do you get and how practical and reliable is it on a long road trip? Oh, well! ...to each his own! My goal is a stealthy, reliable, pump gas friendly and relatively economical road cruiser that is also capable of kicking some ass in the quarter mile! Engine Details, Etc.: 1970 XF code, 4-bolt main, 455 +.050 (467 cu. in.) Stock Nodular crank turned 0.010 Cleavite bearings Ross Custom flat top pistons Hastings file fit rings Eagle forged H-beam 6.625” rods Zero decked 9.5:1 comp. ratio Melling 60 psi oil pump Balanced rotating assembly SFI balancer Fel-pro gaskets #96 heads, ~96 cc, hardened seats, gasket matched, blocked crossovers and mild porting Ferrea SS 2.11 / 1.77 valves 1.6 ratio aluminum roller rockers Comp XE 274 cam 230/236@.050 523/529 lift w/1.6 rockers 110LSA Comp Cams timing chain set, hyd.

PST polygraphite front suspension kit MBM power front disc brake kit OMZ Racing seats Hurst Line-Lok Highway Performance: Getting close to 20 MPG @ 70 mph cruise at 5% throttle! -Runs nicely on the 91 octane oxygenated crap gas found here in Phoenix. ¼ Mile Performance: Only 1 trip to the track so far; ET 13.05 @ 107 mph with a momentary starting line bog and resulting lousy 60 ft. times. Pulls very hard thru top end! More tuning needed w/TBI at launch. -Looking for mid to upper 12’s?! …Stay tuned! Weight: ~3700 lbs. w/ driver
