Thanks man! Working on a 68 Chevy Truck now. Hopefully the LS1 will be dropped in soon.

Thanks guys! It's pretty fun to drive now that I have the tune down. Can't wait to get the Nitrous back on it.

Great looking truck.! I just finished 1994 extcab stepside. looks about the same. Almost.! I can see that you did not have to change the air compressor from the origional position. my frame was too narrow and I had to put a Sanden conversion from Hot Rod lane. Did you modify your frame.? Also I see that you have installed a second master cylinder. Why.???

**Nitrous** · 08-21-2006, 02:38 AM

Hey, thanks! Yes, I modified the frame to keep the top of the motor clean. I looked at the S&P compressor but I decided to go this way instead. It wasn't hard to do and I was able to TIG the frame and use a 5.3 truck compressor. To use the truck compressor I machined another serpentine groove in the balancer towards the front and used a truck pulley. It was easy. I only have 1 master cylinder, you probably see the ABS controller on the fender well.

1/4 mile times? HP? TQ?

**Nitrous** · 08-21-2006, 05:06 PM

I have no numbers yet because I've been pretty busy. I'm hoping the truck is in the 375 - 400 HP range and will run low 13's on motor and 12's with nitrous. I've gotta get some numbers pretty soon. Cooler air is just around the corner.

**tmarr11** · 08-26-2006, 10:02 PM

Seriously, all the best to your efforts. I know that 375 - 400rwhp is pretty hard with all the drivetrain loss of an extended cab. Looks like you've got DRs on the back? Is that a state of Texas inspection sticker I see (I'm from Texas too).

Absolutely love the picture, thing looks beautiful and mean. Only one thing wrong with the pic - the f150 in the background - lol

nice truck, my uncle has a 94 chevy 4x4 with a 383 in it, (ZZ crate motor) it runs as hard as my V10 dodge, which isn't even close to stock, he's down into the mid-13s, again nice truck and keep us updated on the hp/tq and E.T.

**Nitrous** · 08-28-2006, 10:40 AM

Thanks for the compliments guys! Yes, I'm a born and raised Texan and live in H-Town. When I get time I'll take some more pics without the F-150. LMAO The 4.10 gears and 3200 stall help out with the HP loss but I'm putting the juice (100-150) back on it to see if I can get it in the 12's. The Nitto Drags are ok but I had better hookup with the Eagle GSC's. I'm going to try out some cheap Sumitomo's just to see how they perform.
