Video: ENGNBLDR Street RV head and 270 cam

[lilevo]

So I picked up a cheap 89 pickup not long ago after a long 6 month search for home depot hauling duty, salvage yard and metal scr@p runs. I put in all fresh hoses, belts, timing chain, oil pump, etc.

I also put on a shiny new street RV head and asked for the "biggest street cam available"

Upon start up the truck had a few codes. 21, 41, 51.

Replaced the TPS, put in a new O2 sensor, and readjusted the TPS to factory spec (that was code 41)

Short term, I will be throwing on a flowmaster 40 and 2.25" cat back at the O2 flange. Long term will be a header.

So here is a nice lumpy cam video before all that happens.

First off, get yourself a Youtube account to post your videos. I really don't like having to download somebody elses files to my computer to view them.

Second, you like that idle? Sounds like it's having some troubles. While you and your buddies might find that "cool" I see the truck as totally un-drivable on the road or on the rocks.

That cam is really more of a "circle track" type of cam. Cam's don't add any power, they simply move the power band around... and that 270 puts the power at the upper RPM range. Your going to have to have your foot in it all the time to feel any real power.

I am one of the few who think a stock OEM cam is correct for these trucks, unless it's a dedicated crawler/off road truck. The stock grind has a good combination of low end grunt while still having some top end pulling power to it.

That said, I understand this is your truck and you can do what ever it is you like. If your happy, then that is all that matters...

cam choices

While it may be generally true that cam swaps just change the power band that is an over-simplification. Cams can have more or less lift--more or less duration--and different lobe separation. Older engines may benefit from modern can designs, bur again generally stock cams work very well for daily drivers. In chevy engines I build for street rodders I use OEM performance cams (cheap) and often bump the cam timing up 3 degrees to keep the power band low. This results in engines that scream at low rpms but lose power above 6k rpm. The added benefit is these engines last as you don't have to rev the snot out of them and they work great for the daily commute.
