Spartan 228/232 with ported 243's ?
 
Hey everyone , I am about to commence buying parts for a ls1 rebuild. Looking at a weekend driver in manual form. Something that will have reasonable street manners, lumpy idle but will perform good enough for 11 second qtr mile times. Starting with cleaning up of block, balancing etc then work way up. I am going to use 243 heads which are ported on both intake and exhaust so I am now choosing camshaft that will suit my goal of 11 sec qtrs in the 400rwhp range and lumpy. I've come across this spartan 228/232 spec cam and am wondering if cam would be what I am looking for with the ported 243's ? Any others I should consider?

You may also want to let the other techs know what intake you're going to use, lbs injector, lt/shorty or stock manifolds, fi or na, compression ratio is also important to know. Just a bit more info would really help everyone out.

Motor will be na. I would use an over radiator style air intake without airflow meter, ported 78mm tb with ls6 intake manifold as a minimum , with 36lb injectors, 1 7/8 headers into merge pipe and twin 3 inch exhaust system with hi flow cats. compression ratio would be at 10.5. Manual transmission with 3.73 gear.

Why not shoot for something around 11:1 compression?

You say you want a lumpy idle...what is the LSA on that cam? The mufflers you choose to run will also factor in as well as running cats or not

It will do well for you. I'm running a similar cam based on his recommendations and have been happy with it.

JakeFusion Apr 1, 2013 03:48 PM

Yeah, Josh's cams are solid. He is a big proponent of using Cam Motion.

228/230 on 112 LSA very similar lift. Drives very similar to stock.

I think that is a great cam for your set up. I run a slightly larger Spartan/Cam Motion cam and love it. The nice thing about those cams is that they do not use those blocky lobes that beat the snot out of your valvetrain and are good high quality grinds.

Im running comp 228/232 112 with tea 243s. Great setup.

+1 It is a great cam. Josh has proven it.

This Josh feller sounds legit.

Keep in perspective that the engine combination is only part of the equation when trying to achieve a certain ET bracket. Weight of the vehicle, gearing, trans, stall converter (if applicable), exhaust choice, altitude of your location, tires, traction, suspension.......Just to name a few, all play a roll in running 11's/10's/etc.

The 228/232 combo works excellent with 243 heads. With the right lobe/ICL/LSA combination you can get around 11.3:1 compression with those 243's and no PTV issues. The old "Spartan" cam was a Comp grind, which is no longer used. All those cams are cut through Cam Motion now.

Good luck.

Yeah, he's legit! :usa:

This shits impressive.

That's a mild ass cam too with only 4 degrees of overlap. You don't need a shit ton of overlap. Get some good heads on a car, run a good cam profile, and run compression. You'll fly.

G-day mate im running a H&C setup in my vy ss its m6 with 3.9,vcm otr with only 1 5/8 4-1s and 100cell ballistic cats twin 2.5 exh and cam is a Howards 228/234 .604 609 112 and it behaves well on the street for a m6 and pulls hard from just a roll on.Get off the clutch hard and its creates bush fires.I made 396rwhp on a Mainline dyno

low2001gmc Apr 13, 2013 03:39 PM
