Can you get this thing into the 10s with the current powerplant?

Yea with the way it ran last fall i think the 1900 could get me there... I don't have a 'blower cam' in it right now and its just stock 317's. I could mod the stock LQ9 just to proove a point... but that seems kinda silly. If the heads and blower are coming off I think I should just upgrade them, no?

I feel confident it had another couple hundreths in it to get me down to 11.3x no question... the problem I have is its a lot of "if" and "but" ricer math to say it has 10's with something close to the current combo. At the end of the day is it impressive for a maggie or other PD blower to run 10's, or just the 1900?

I think its impressive because its a relatively simple setup in a big heavy crew cab truck. I know a lot of it seems to be attributed to your tuning skills . Either way its impressive in my opinion.

Speaking of tuning, do you tune this animal yourself? HPT or EFI?

So I replaced the chain in the transfer case, but the old one was totally fine. I replaced the rear bushing and the tail shaft seal and the vibration is gone! Man was that long overdue!

I had the truck out the other day and its running as strong as ever.

I have been planning through 'stage 2' for this truck... ill keep you guys updated as things firm up a bit.

Speaking from experience, better stop now while it still works!

Yup. And 4200 is being nice. It's way too loose IMO, but its as tight as they make them.
