c10 with 325/50/15
Not that anybody cares... lol
I searched and searched for information on the biggest drag radial and wheel that could be run on my short wide. Some said 15x12 and others a 15x10. Then there where the tires sizes I found some ran the 315’s and others 325’s. And then I wanted pictures as well...
I finally bit the bullet and settled on a 15x 10 wheel vintiques with 5” back spacing (I painted them black) and a 325/50/15 bfg drag radials. I went with the rallies because when I bought the truck it had damn good tires on 15x8 (I think) rallies. And I liked the look of the black rallies on the truck. I have used the bfg’s on previous projects and they worked well and lasted decent. The only issue I’ve had is that when the suspension is flexed and on rear tire is up and the other down. On occasion when turning into my driveway from the street the tire rubs the inside of the rear fender well a bit... Just enough to make a squeak...
Anyways here is the pics. I hope it helps someone.

I bought the truck some months ago from a member of this site:
chevyguy7802
Its a very soild truck, I bought the truck and drove it 3.5 hours home after purchase with no problems. I've added the rear wheels/drag radials and a full set of autometer gauges.
The plans are l92 heads,lntake, 92 mm tb and maybe a bigger cam. I wanting to run mid 12's with the street set up.
Thats all the pics I've taken soo far.
The truck has around a 3/5 drop on it I believe. Coils in the front and a hanger and springs removed in the rear.

Well I went to the track this past weekend with my 1978 with the LQ4/4L80E, and my assumptions were correct. I need trac-bars BAD. The rear end rapped pretty bad and it wheel hopped from a hard dig. There was visible damage to the u-joint strap bolts, because the bolt heads made contact with the drive shaft at some point. When the truck was lowered they used aftermarket hangers and removed leafs and a wedge to rotate the rear for pinion angle (non-flip kit). So the leafs are pretty weak.
I rolled it off the line with the drag radials (325/50/15) at 14 lbs and the truck went best of: 12.87 @ 105 with a 2.00 sixty foot. I played with the truck off the line and went 12.99 @ 105 and 12.90 @ 103
If I can get the sixty foot down I'm thinking 12.50's
My plans are to build cal-trac "like" bars.
I need to order the solid spring eye bushings, I've already bought the heim's and got some scrap metal around the shop. So now I just need the time to build the damn bars.

I had a set of chrome steel rims 15 x 10" with a 4.25" BS with the same BFG 325/50/15 DR's on my 96 rcsb. The tires stuck out of the wheelwells a good 2-3 inches on both sides.
If I had a 15 x10" with a 6.5-7" BS, they would have fit better, but good enough for the drags and were only $40 a piece.
You nabbed a 2.0 60ft and ended up mid 12's. I nab a 2.0 60 ft and got a high 14 lol, amazing the difference.
On your 78, do you have a 12 bolt 8.875" truck rear, or the coporate 8.5" rear?
Stance is nice man.

This past Friday I finished my trac-bars and got them on the truck. Then Saturday a group of buddies and I went to Pinevalley raceway in Diboll tx, to hit the track.
Well, the trac-bar worked well but did not drop the 60-ft at all. The truck ran 13.0 @ 103 numerous times and acouple of 13.1's. I tried leaving on the 3000 stall and even shocking the truck off the line to improve the times... Nothing was working. I even let a buddy pilot the truck acouple times to watch the truck leave. With the preload on the trac-bars the truck would wrinkle the drag radials (12 psi air pressure) no spin AT ALL.
I've talked to some freinds about the performance of the truck and everyone seems to think the truck is hooking up so well that it is bogging the motor off the line and killing my et. I think when the truck was spinning alittle the truck would get the rpms up, and stay in the power curve. Hell the truck was running 105 trap speed.
So the plan is milled L92's, L92 intake, a new comp cam 224/236 .581/ .601, and 92mm Nick williams throttle body and tunning. I've already got the said parts, I was planning on using them on my 94 ecswb with the Lq9.
