    Jeff, I saw that you had traction issues and so did I. Other people seemed to hook well. Anyway...your car looked and performed very well, even though you had those traction issues. That's a nice ride you have there!!!!! Once you get the 60' figured out it'll be killer also!!

    Thanks to all. I thought I responed yesterday but i guess not or i will be repeating myself. Car weighed between 3100-3200 with me in it. We were all surprised at how much weight came out of it without getting too drastic. Here are the stats.
    Best 60' was 1.222
    Best 1/8 e.t. was 5.46 or .48 (Dave has all the time slips)
    Best 1/8 mph was 124.8
    Best 1/4 e.t. was 8.68 rolling out of throttle at the mph cone.
    Best 1/4 mph was 152.0

    If you saw how the car launched on Saturday you'd never think it would hook but I love those Hoosier radials. It would plant the wheelie bars and lift the front about 2 inches. Racepack registered a little over 2g's on the launch. I had to use the transbrake to activate the launch retard but never came up against the launch rev limit. Wanted the chassis relaxed but didn't want to shock the tires too much. This gave us repeatable results.

    Car drives very straight. Only scary part is that it breaks the tires loose a few times around the 1000 foot mark as if hitting bumps in the track.

    Jeff it can be done. You have a very impressive car. It caught my attention in the pits everytime it went down the track. I only saw one launch, chassis didn't budge, just blew off the tires. Sounds like you finally got a workable set up. You just came to a place where you now had another 50 or more horsepower to deal with.

    One more thing Bruce, if you do not mind Bore and stroke?

    Building a 4.375 B x 4.3 S do to having the crank, would you think it would be worth the extra expense to go with a new crank to max it out to 4.5 x 4.5. Engine shop is concerned! they have saw HP losses in Chrysler's with this sleeve when going from 4.375 to 4.5 dia. even though manufacture clams no issues.

    Is the B1 you used an old none welded flange that has the same angle as the Buick or did you weld it?

    Thanks Wayne Roberts

    Bruce the car was damn impressive. Nice job getting it down the track all weekend.

    Jeff I have to say that your car is a beast. Very nice car.
    We were fighting some traction issues at first as well but I wasn't sure if it was track prep or all the suspension changes we had made. The radial slicks weren't happy at first but we ended up taking 2lbs of air out and the car responded w 1.37/.38 short times after that.

    For me it wouldn't be worth the added expense. You can make plenty of power with what you have. This engine has a 4.380 bore and 4.5 stroke only because we had existing parts. No adapter plates on this B-1, they did some welding on it.

    hey Bruce what size and whos convertor are you using?
  19. Bruce Kent

    Bruce Kent Well-Known Member

    The converter in the car is a 9" ATI. I've also had great luck with A-1. This is the first time we've had a properly matched converter with the Apollo. Every time we put an engine out of a GS into the Apollo they tighten up by 500 rpm because of the different headers.

    Which heads are on this engine? Who did the port work?
