383astro

I built a Mild 355 for my 88 Iroc Convertible but ended up buying an Iron 6.0 for it. I am thinking of putting this motor in my Astro van to build a comfy tow vehicle out of. Let me know what you guys think about how reliable and street happy it would be. I hate for the motor to just sit there on the test stand and the Astro 4.3 is getting a little weak (has about 280K on it). Here are the specs.

350 4 bolt bored .030
Stock rods, polished, ARP bolts
Speed Pro Forged Flattops
Stock cast crank
882 heads rebuilt with aftermarket springs, SS valves and locks, mild cleanup on ports
Comp Hydraulic Cam .507/.525 284/305 113 Nitrous cam
Geardrive
Has a Single plane on it now but have a Dual to put on it
Holley 750 Vac
700R4, 3000 stall

not special by no means but I wanted it for a cruiser
What you guys think?

Then you'll want to yank the big nitrous cam in favor of something along the lines of a 21x/22x duration @.050" and use a timing chain unless you like the gear whine. Downsize the carb to a vac 600cfm, dual plane intake, 1800-2000 lockup converter, 3:73 gears. There's your comfy tow vehicle.
