I'm not a big fan of Airtex or Carter Fuel pumps. I would have grabbed a Delco. They just seem to out last the rest.

clinebarger · 12-12-2009, 07:04 PM

You may already know but you need different clamps and high pressure hose between the pump and sender, The low pressure hose will blow or the plastic clamps will give, causing a major fuel leak inside the tank.

i'm planning on the same radiator... but i gotta look into this. http://hotrodlane.cc/77chevytruck/77chevy.htm

apparently you can order the fans to go with the radiator.

btw, (if you dont mind) how much did the radiator alone set ya back?

here's a couple more options too...

oh yea, the intake runners sure look clean for 70k!

how did you gettem looking like that??

clinebarger · 12-10-2009, 05:23 PM

Those are not 98 model heads 97&98 LS1s had perimeter bolt valve covers VS the center bolts on the 99 & up

3r!c84 · 12-10-2009, 05:38 PM

he said it has ls6 heads

clinebarger · 12-10-2009, 06:18 PM

There not LS6 heads either. LS6 heads have a 243 casting number. It looks like 799 on these or 79somthing

mud.man.rj · 12-15-2011, 12:57 AM

LS1/LS6, I still think it is a great undertaking and will be nice when it is done. The LS series spin up real nice, just traded my 2000 Trans Am WS6 for my 71 GMC, really liked the LS, good for you. Can't wait to see it finished.

yeah there 799 virtually the same as 243 casting. The exhaust port is D-shape wich come on the LS6

smokedat · 12-10-2009, 06:39 PM

Belt, A/C compressor, and power steering pulley are off. Waiting on the A/C relocator pwr steering pulley and belt.

smokedat · 12-10-2009, 06:46 PM

There is no difference between the two heads. The numbers tell what original mold the casting came from. 243 mold was done at GM Research, the 799 mold is used by other vendors. The same vendor will have 243 and 799 molds. The numbers are just a GM system for when the mold was made. If a head had a problem it helps them track down where the problem started. The only difference between the heads is production variance.

I did not know that. Out of the 100+ LS6/LS2s ive seen/worked on they all had a 243 casting number. are the heads production? Or a GMPP part?

smokedat · 12-10-2009, 06:50 PM

menace121978 the radiator was 700 shipped 645 with trans cooler w/o 595, as for the clean up I used regular break cleaner works good.

# Type: 45° Flaring Tool
# Maximum Pipe Capacity (Inch): 3/4
# Minimum Pipe Capacity (Inch): 1/8

menace121978 · 12-10-2009, 08:18 PM

just remember for the AN fittings they use a 37* flare. brake lines and such use the 45*.

my 45* is a craftsman and i'm really happy with it. right around $80. i had bought 2 cheapo ones from orielly and broke'em both.

i'm going to order a summit brand 37* for the an fittings.

smokedat · 12-10-2009, 08:24 PM

the best one by far is this but its more expensive

smokedat · 12-10-2009, 08:26 PM

menace121978 · 12-10-2009, 08:27 PM

Whoa!

smokedat · 12-10-2009, 08:27 PM

"Dennis the Menace" i agree the cheap flaring tools just don't work especially on stainless steel

smokedat · 12-10-2009, 08:31 PM
