Thread: My rusty/ratty 48 chevy truck build (w/ pics)

Tweet

I pulled the motor to fix some oil leaks and while I was at it, I swapped cams. I took out the 350 horse 327 cam and stuck in the second smallest Lunati Voodoo cam.

Broke the cam in to Lunati's directions...20 minutes at 2500 rpm then 3000 for 1 minute, then 3500 for one minute.....then was supposed to work down by 500 rpm steps for 1 minute.

While doing the 3500 rpm step (21 miutes into breakin...in the driveway), a hoseclamp on the lower radiator hose failed and the lower hose blew off of the water pump.

Not sure if it cooked the rings or cracked/warped the heads.

If this motor craps out...I have a good guess as to why.

Turns out my initial valve adjustment was wrong. Don't know if i didn't pump up the lifters enough or what. I re-adjusted the valves while the engine was running and all is better.

From this years Bunny Run

A few pics I snapped last weekend ....just because I had a camera in my hand.

In an attempt to get better gas mileage, I swapped the 750 carb and high volume pump for a 600 carb and stock fuel pump.

Truck still runs decent even with the smaller cam and carb.

It ran a best of 8.74@72 mph in the 1/8 mile at the Dixie Dragfest. I couldn't leave at anything above idle or else it would blow the tires away. I made 8-10 attempts at a decent launch and then quit trying.

I'd be curious to see what it would run on slicks mounted on 15 wheels.

Looks great sitting on the strip!

Heck Flip your truck looks so cool and those big hoops and rubber bands really suit it, And that sir is a compliement as normal big wheels and little tyres like that only suit late model cars but ,man you have nailed that prefectly. Love the finished paint job too.
