very nice. i see you had to lose the fins on the lower valance to put in the intercooler piping. most wont see it until she's carrying the hoops or changing the oil at a service station. alos with that much bite on our heavy yatchs, how the battle boxes holding up? looks like your using lakewoods or southside machine trac. bars. i know the ssm bars are hell on ripping out and adding damage to the battle boxes.

Are those widened Bill Blass wire spokes in the back? If so, thats just completely awesome.


How much boost and rpm are you running that its popping head gaskets regularly? I'm guessing you've verified the deck and the head surface are properly flat and all that good stuff?

I didn't have to lose the fins. I pulled that and the front license plate at the track as an experiment to get more air to the intercooler. Unfortunately the only place to put the intercooler placed most of it behind the bumper. I'm going to build a small scoop to direct more air to it. Otherwise I may try a nitrous or CO2 spraybar at the intercooler. My air temp in the intake is 170 at the end of the track on a hot day. I'd love to see 130. The torque boxes are not showing any signs of stress so far. They're tied into the subframe connectors that I built. The traction bars are a set of Lakewoods with an adjustable strut rod and poly bumpers. They hit reinforcement plates that I put in. They are modified Mustang bars. I moved them inboard to clear the air bags which put the snubbers directly under the frame. They don't bolt to the lower control arm mount like they would in a Mustang after I moved them in so they're welded to the axle tubes. They work way better than I had hoped. I didn't expect the "yacht" to pull the front wheels with no tire spin. The car is full weight: A/C, power leather, etc. plus the framework and cage. I boxed all the stock control arms and reinforced the bolt holes and use poly bushings.

It is air springs too. :) I had a feeling that it would make a great drag suspension. There is no more ride height control unit. If you can find my gallery there is a picture of the trunk. I have 4 switches to open the bag solenoids and 4 air gauges with schraeder valves. I run 80+ # in the front for weight transfer and about 50LR and 60RR to weight jack the suspension. You can thank the track photographer.

Yep I widened the Blass rims 2" and then had a spacer machined which I welded to the back side to push them out 1/2". I'm running 11# at 6500 rpm presently. The first time I blew the head gaskets was a combination of too much timing in my computer program and not enough octane. As soon as the motor sees boost now it pulls 5 deg of timing. By 11# it has pulled 11 deg. The second time I blew the head gaskets was because the small brass fitting that I had screwed into the upper intake cracked and broke off from vibration. That line sends the signal to a 3 bar MAP sensor that tells my engine management system to pull timing. Bottom line: at the end of the track under full load and 11# of boost, 11 deg. of timing got added back in instantly. That's a recipe for disaster. The 14# blower pulley is sitting in my desk drawer. I'm going to enjoy the car for a few more weeks (and try to get better at driving it - it's quite a handful) and then pop it in. We're gonna have a stock bodied 10 second Mark VII .....or one angry track cleanup crew. 8-)

I imagine that must get some people bothered, getting beat by a car with power leather seats and working AC.

It is a trip. Everything in my class is full race, no license plates, all stickered up, big slicks, no exhaust, etc.

I actually had the 14# setup on it in the fall, but the track didn't open the last couple weeks because of weather. If I was gonna scatter the motor I wanted all winter to build another one. I shoulda anyway. The next one's a 406 or more on an aftermarket block. Shoulda done that the last time. We're flirtin' with disaster as it is. But anyways, I had also gone to a wider/taller tire before the boost increase because I was running out of RPMs at the top end. The new tires net a 7% gear reduction plus we were also needing a little more contact patch. That (I think) coupled with some MAF sensor problems slowed the car down a half a second. If the lost ET was all in the tires that's OK cuz we'll overtake that plus with more boost, but in the interest of keeping track of what's happening I turned the boost back down to 11# and I'm having a set of steel wheels widened to put the shorter tires back on. I want to get the car back to where it was (11.34) and then make one change at a time. Our track was supposed to open 4/16, but like much of the country it's rained for over a month. I might get down ther Wed. for opening night and see what she's running now with the 11#, a new mass air and the tall tires (cuz the guy's had my steel wheels for 1 1/2 mos. and they're not done yet. So much for planning ahead.) I did install a Detroit Locker and 31 splines.

Made it to the track Wed. Tried my other ABACO MAF. Best of 11.87 still with the tall tires. A/F ratio at 11.0:1 on the best run. The more I leaned it the faster it got. Might lean it once more to 11.5:1 with good gas.

Keep at it, make us believe the stock block can do fine if tuned right. :P

BTW, could you use a Dart 302 Sportsman block for about $1850, it's in Illinois? New.
