I install the kits every day, 42 will be more than enough for my LT1.
I only use 60 in the LS1 600+ cars. I have a 255 walbro pump.

I don,t mind to lose a race, theres all ways some one faster.
But, there are those loud mouth guys out there that you know
you can,t lose to or you will never hear the end of it.

The 50shot works great w/ the setup. It gives about 100hp on the
dyno. Im shure Ill be building a motor soon.
But still theres a lot of are cars running around on stock bottom ends
that make over 500hp.
The bumper is a temp. till my custom bumper is done.
The speedo in my car only goes to 115. Ive only seen 2 other cars w/
it, every one else has the 150. On the 150 cars the speed limter is
147 unless you have had some sort of edit program done.
Here is a pic of the guys car who is making my bumper.
