I think it is BS the rednecks will not allow the LS with stock heads and a MSD ignition. It is cheaper than going SBC, last longer and the SB Chevy is getting harder to find in decent shape. Not to mention they won't hold rpm without arp bolts and supporting mods.

Guess they will have no choice eventually. 5.3 are everywhere and highly capable. Not to mention the 4.8 will spin 7800 with no problem with a cam and springs.

Just haters.

Yep, I built it after-hours in the shop.

how much you asking for the engine without distributor drive setup?

It kinda has to have it, there's no reluctor wheel on the crank and all the sensor holes are plugged.

Id put a full MSD crank trigger setup with belt driven distributor on. So how much?
Just like my buddy's car

I'm in the process of putting an LS motor together for a UMP modified. I know I have to run a distributor but I'm not sure which way to go. The belt driven? Or buy the front cover and run the ford distributor? Neither way is cheap. Which is better?

Pretty gnarly looking, dirt racing is fun bc there ain't no lifting of the gas lol

orange88ls1s-dime

I would go belt drive dist ,way better setup

Why is it way better ? Also whats it cost ? Whats needed ?

II've seen a couple instances where the Spud on the cam came free and did some damage in the front dist app . Plus the belt drive setup works well in high rpm apps and under lots of up and down abuse.

Thats the steam line I'm getting ready to do....just need to pick up some 1/4" tubing.

you should port match the intake to heads. im sure that is worth a little bit. i saw someone who did a port match for his vic jr to his heads and it was RETARDED how off it was


super bad *** btw

13:1 compression on a ls, wow. I bet you want have any problem keeping up with bigger SBC engines.

Awsome to see an LS in modified. Hope it takes off in dirt track. What kind of valve train are you running?

Nice work on the steam pipes. Curious... I read that it's best to run it to the top of the cold side of the radiator so all the steam goes somewhere. Running it to the top of the water pump can allow any steam to collect in the pipe... any experience with this?

I ask because I'm about to put a carb'd LSX in my father's Panoz and am having a new dual pass radiator built with a provision for the steam pipe vs. just putting it to the water pump as others have.

Doug G

Some say there is no steam, its just a vent line to allow the coolant to fill all the ports so no air is trapped.

As for where the line gets hooked...I think on the suction side of the pump is just fine.

Interesting... always heard them referred to as steam pipes used to get any air created out of the heads from hot spots when racing. If there is no steam then plumbing to the water pump would be fine, but if that were the case then there'd be no reason to have the older style LS1 pipe that uses all four ports.

We also did another LS for a dirt car, a Super Stock is what we call them around here, a 3000lb 2nd-gen Camaro. It was a 427 in a LSX block with a set of worked over iron heads, solid roller valvetrain, Super Victor, distributor cover with a DUI HEI in it. We plugged the vent ports in the corners of the heads, ran no water crossover what-so-ever, had ZERO issues. I think the whole steam thing is over rated.

I think for dirt track racing the distributor conversion cover is better because everything is contained inside, versus a belt drive where everything is exposed to potential rocks and debris from the track. Drag racing would be a different story though.

My complete engine is for sale, BTW.
