I've got a '68 Sweptline. When I got it, it already had a 440 transplanted into it. I ran it for a couple of years (over 2.5) after putting Eddy heads on it (in my carport working over the fenders). Last week I broke the crank behind the #4 main, probably from running too much timing because I never bothered to tame down the mechanical advance in the dizzy.

Long story short, I've had a 440 sitting in a barn completely buttoned up that I bought about a decade ago. I took it apart this weekend and it had recently been rebuilt (though ran) and looks great. I'm going to swap the heads over but was wondering what you all thought might make for a good cam.

Current setup:
* Shorty headers ('68 pickup frame means you buy very expensive long headers or make your own)
* Eddy heads with 84cc chambers
* 750 Holley
* stock rockers, aftermarket lighter push rods, stock lifters
* stock converter going to a 727 ('68 from a c-body)
* Unsure of rear end gearing
* I believe pistons are stock replacement (meaning 0.050 in the hole) but will check later today
* Eddy performer RPM intake manifold

I know I'm forgetting some stuff but that's what comes off the top of my head.

The pickups supposedly weigh less than a b-body but more than an a-body. I've never weighed mine so I don't know for sure.

The truck is street driven, often goes to work (in terrible Atlanta traffic), is used to run to the lumber yard from time to time, and serves as a weekend cruiser. I'm thinking of one of the following two cams but wonder if they are too aggressive for what I do.


Comp Cams XE275HL-10
or
Lunati LUN-60304

I'd use the lunati voodoo 60303.

Yeah, after taking to the machine shop, the smaller cam may be the way to go.

the 603 is a better choice for a driver. 604 wants a bigger gear and more stall in an auto. Also wants more comp and bigger carb. I got the 603 and it's super. Ton of low end torque and pulls hard to 5800. Thats enough RPM for a driver big block.

The engine this cam is going in was rebuilt over a decade ago. The pistons look brand new (it hasn't been ran in a decade either and clearly not for long when they did run it). They are real flat top replacement pistons (0.02 over and .100 in the hole). So I won't have 10:1 compression with the head gasket I was planning on using and without a dish in the piston I'm worried one of these cams may introduce the valves to the pistons. Might have to go with the 509.

Thoughts?

509 would be a freaking terrible choice for your combo. I run the lunati 60303 and it's a great street cam. As streetable as a stock cam. I don't think you're going to have any piston to valve issues with that cam and your pistons.

Sounds like the 60303 may be the ticket then.

Here's the bottom of one of the pistons. Piston looks new. The rod bearings are not so lucky.

603 is an excellent choise. Very streetable. Makes good power with lower comp motors. The 509 as stated would be a bad choise. It also wants more comp more carb and more stall.

Sounds good. Just realized these stupid pistons being .1 in the hole will have me closer to 9:1 compression rather than 10:1. Time to look for a different gasket.

What kind of lope does the Voodoo 60303 have?

I didn't rebuild the engine myself. Someone else rebuilt it then the guy I bought it from got it from the person who supposedly had it rebuilt. I bought it over a decade ago when I got my Superbee basket case (it was part of the deal). I never ran it and never [Edited by Moparts - Family Friendly Site - Keep it clean] it apart. It sat on a hay wagon completely buttoned up until Saturday.

Currently, the engine is completely disassembled. The rod bearings are shot, the mains aren't great, but the cam bearings look okay. They may be replaced too. It is doing to damn near be a complete rebuild. All but one of the cylinders looks great and I'm hoping the one will clean up with a slight hone.

Don't worry, we're taking care of her.

Good move on the complete tear down. You might want to look at having the rods resized ( or at least checked ) and also checked for straightness.
