70 GMC 355/142 mini blower track results - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Posting for my buddies truck. He posts on here as Jslater I think??? Anyways we put a 142 miniblower on his truck awhile ago and finally got a chance to get it to the track. N/A its best pass was 14.79 at 91.5mph on 27" street tires. This time added the 142 miniblower and 28" drag radials. Track condition were fair and had about a 10mph headwind. Right at 4200lb race weight.

First pass...27 deg total with muffs on...........13.78 at 96.5....1.94 60 foot

2nd pass....same set up...better launch..........13.56 at 96.6....1.90 60 foot

3rd pass...29 total.......................................13.54 at 96.5....1.89 60 foot

4th pass...29 deg total...removed 2.5" Super 40's....13.40 at 97.6....1.87 60 foot

We made a couple more passes after this but the track went away and it was getting slick.

All in all he was very happy. Not bad at all for the 882 smog heads with 1.94/1.50 valves! Next he needs to get some bungs welded in the exhaust so we can see what the AFR is doing. Then plans to replace the 2.5" flows with some 3" highflow muffs. Also remove the snug lid and tail gate to drop some easy weight. Should see some solid 13.1-13.2's soon. Then he plans to put some decent heads on it and run solid 12's. Might also need to address the converter. I calculated it out at 13-14% slip. I think its eating up some of his trap speed.

Guys with 12-13 second trucks how much mph are you picking up from 1/8 to 1/4?? He is picking up about 16.5 mph or so.

Thanks for the reply Zach. Looks like you are picking up about 17.4 from 1/8 to 1/4.

Good lookin truck

BTW i ended up ordering the XE 294 this time around

He'd probably pick up a bit more time losing the big tires/wheels, rolling mass hurts et's as well. Is it spinning, I am guessing not with the 60 foot times, but a lighter tire and wheel combo may help the et but could lighten it up enough to cause some traction. BTW the truck is sweet and I like to see guys keep the 4 eyes instead of changing to 2 (GMC vs Chevy).

That XE294 is a big sucker....might need some more converter with it....

Yeah...he was planning on going to 15's but the truck already had the wheels on it. So he just grabbed some drag radials and slapped them on. Once the tires wear out I could see him selling the 17's and going with some light weight 15's.
