Cam swap time

[RCSB91]

whats up guys, Im working on a 91 K1500 single cab short box, has a carbed 91 350 (stockish TBI heads) with headers, dual plane intake, 670 Holley DP. 5 speed trans, truck now has 3:73s... looking for a good all around cam, truck will be daily driven, and I do tow once in awhile, I want both power and sound, I dont need all the chop but I do want to be able to hear the lope... what are some of you guys running???


Thanks -Phil

Lunati 20080720 (roller cam, Vortec heads)

In the old motor I took out, (TBI block and heads, no roller provisions) I put a $50 Enginetech ES179R cam in. It's still on the build stand. Supposedly it's a copy of a late '60s Corvette cam, fairly choppy, and crappy gas mileage.

I should mention, it requires headwork or beehives.

Choppy cams and trucks don't really go together, unless you're intending to race, in which case you'd probably be swapping heads and getting a different torque converter. IMO look for a cam that fits your intended rpm range, you'll be happier with a truck that performs well.

Just tune it like **** in the idle area and it'll sound like its choppy haha.

really dont want the chop, just want a little lope, I do have a set of Vortec heads that i was going to use for something else but since I need my truck the other project can wait.

Hopefully one of the 350 guys will chime in with some cam ideas.

ive been doing some looking on the interwebs and im looking at a Comp 268xe cam

Here's a Lunati cam that is a little milder but will give you good torque at the lower end of the RPM range for towing. It's still considered "computer controllable" but, that Comp cam can be computer controlled too, with tuning. I'm running the 10120700LK with 1.6 full roller rockers giving me ~.464/.484 lift (208/213 @ 0.50") with Summit Racing 162109 Aluminum heads (which flow a little better than Vortec heads). It idles smooth but you can hear it's not stock with my 3" Borla straight through muffler, ha ha. Personally, every upgrade (cam, heads, etc) I would tune it for optimum performance/mileage.

The 10120702 is more comparable to your pick AND it's in stock @ Summit Racing. With the Covid there's not a lot of cam cores floating around right now so, you don't know when you're gonna get one if you order it.

Anything 215 deg at .050 or less should be fine for duration and streetable.
