Ls1

This guy I went to see today also had 2 LS1's that He was trying to sell as core's, He wanted 200 each for them too.....

I thought about gettin them just to have 1 But I can't remember if there is any way to run them with a carb???

Do they make an intake to put a 4 barrel on LS1 heads?? Is this an expensive conversion?? Is it even worth while??

What other benefits do they have other than the reverse cooling system over a GEN I or II

6 bolt mains, Cathedral style intake ports for great flow and velocity.

Advantages?

My LT1 (functionally the same as a Vortec) looks like this: 10.25:1 compression, 260 hp, 20 mpg with 3.08 rear.

My dad's LS7 looks like this: 11:1 compression, 505 hp, 27 mpg with 3.42 rear.

I would say there are significant advantages, not the least of which is weight.

GM offers carb intakes for LS1s too, GM PART # 88958675 . I'd keep it EFI but that's just my preference.

I'd spend some time over at LS1Tech.com to read up on these amazing motors.

What were the LS1 specs stock?? cam grind/pistons/ chamber size/ runners/ CR/ HP/ FTLB TQ ect.....

I see the eddy intake comes with the timing control box, I've never messed with more than an HEI, Are these hard to figure out, Can I run it w/out a computer??

Download the GM performance catalog and look at all the LS series crate engines, it should tell you everything you need.

There are parts available to run a LS series engine with a carb and a distributor, no computer needed. I would imagine the new front cover and associated parts are $$$

They are in the GM Perrformance Parts catalog, or they are available from your GM Performance parts dealer.

My next project engine. LS2 with L92 heads, GM Perf intake with a FAST 90mm throttle body. I plan on a 4" stroke for 408 cubic inches. I think it will probably make close to 450 hp at the rear tires. It will be replacing a basically stock LS1 in my 1935 Sedan.

diff GEN's

Thanks for the info exchange, but its not the different styles I'm interested in but rather the different types of ignition systems you can run on the LS1.

I don't even see a place where a dizzy would go, If you enen can infact run one. Where would it be located and what manifold would have the nessecary holes/whatever???

There is no distributor. The LS engines use a crank trigger for timing. Download the GM catalog like I mentioned earlier and read it. Gm makes an ignition controller to run a carb its part number 19171130. It's

"Distributorless plug-in ignition system for carbureted LS engines with 58X reluctor wheel. Supplied software allows you to create custom vacuum advance curves, timing curves, program lo and hi rpm rev limiter and more! Compatible with LS1/LS6 and LS2/LS7 ignition coils.

And the carbed intake is 88958675.
