They were a Goodyear Eagle II 245R70-15 for the street at all four corners and a set of Hoosier 32.0 x 14.0-15; bias ply slicks at the strip.

hahaha thats awesome Dave! I'm not worthy I'm not worthy I'm not worthy


a little update....

made it to the track over the weekend. apparently, the issue on the dyno was more than just a bad part.... the head had to be repaired so it went back to Dart. obviously, the builder just stuck it on without checking anything....

it broke #2 intake rocker on the dyno. builder figured it was just damaged from the previous carnage. so, he sent us the motor and had the new rocker and pushrod drop shipped to us. i put it on and it seemed to take quite a bit of adjustment. but, what the hell do i know ? im just a tuner
retard . anyway, we get to the track friday and make a T&T pass. it ran really well. saturday, we're in the staging lanes for the first qualifying pass. rolling up to do the burnout and we hear KLAK-KLAK-KLAK-KLAK-KLAK..... shut it down. go back to the pits and find #2 rocker broke. i send pics to the builder, hoping for some helpful insight and the response was "it must have came loose" Evil or Very Mad .
today, i pulled the engine and started digging. got the head off and sent it to a local guy to do some measuring. turns out, that valve was over .100 too short...... wrong phucking valve!!!! it was binding up . needless to say, the builder is going to get an invoice.

Wow! Shocked I'll take my coil circuit issue over that all day long. Damn that sucks. I would send him an invoice. That is the dumbest thing I have heard and engine builder do in quite a while. Shocked

My guess is he installed the heads as they were received right out of the box. The valves in these heads are frequently sourced from India or China, and are known to crack where he head is friction welded to the stem (unless you pay extra for Ferrea or Manley valves).

The valve job in the head is performed by a CNC machine, but if you look at the valve there may be a three angle valve job but most I have seen were only a single 45 degree. They are never lapped in.

It is easy to throw a 0.100 inch under length valve stem just from eye balling it. I don't think they have their machinist assembling heads when there is so much cheaper labor available in every American city.

I buy my heads bare and assemble them myself from parts I sourced, then do a five angle valve job after they are ported.

i think our builder was over his head on this. i honestly dont know why he didnt check everything when he got the heads back. its his name on the build and his reputation at stake. i dont have to say a word to anyone and he gets a bad rep..... his name is all over the car and trailer. when we go to two consecutive races and cant even finish qualifying, people take notice.

My guess would be (using my Robin Williams as the Gennie in Aladin voice) A really big motor in a teeny tiny living space.

BBC has a urine poor (only using the P word) exhaust port that makes a ninety degree bend in less than two inches that is then aimed down at a forty five degree angle at the frame and inner fender well. They were designed to fit in trucks and buses and big cars that have more room under the hood than Chevelles or Camaros or tiny Anglias.

I assume the owner wants Zoomies for cosmetic reasons as a tuned exhaust with collectors will make more power.

as usual.... absolutely correct Dave. although, there is a secondary reason for the zoomies... it gets the meth fumes outside the car. driver says he cant hold his breath that long. Laughing














dont know why that first pic is oriented wrong. its supposed to be turned to the right Confused

I would be making a cast of those headers when you pull them off to fully weld them up (using Plaster of Paris in a wooden box). As the first time he kisses the wall he will need to replace them. And it is gong to be just as hard the second time around to build them from scratch. if you don't have a pattern to lay pipe in and tack weld the segments together.

Those look great! I'd trade the task of building those for the ones I had to build on the Chevelle any day.
