so first off my old setup was a 346ls1 with a ms3 on a 112lsa. with stock ls1 heads and pacesetters. and my new setup is in sig. my new setup is not tuned yet still only have 150 miles on the new motor/clutch. but my ms3 setup was alot louder and more choppier. this setup is now quiet and not even that choppy. which is wierd considering my cam is a 240/256 .64x/.64x 111lsa. do you think my tune will make this more choppy? what do you think is up with this setup

 

Maybe it's less choppy because the extra cubes better utilize the big cam.

 

ya thats what i was thinking. it sounds more of a healthier race idle then before. no complaints tho bc it deff is alot faster.

 

what heads would you guys recommend for my setup? this winter i want to get better heads and a used FAST 92/92. i was thinking of sending my 243s out to save some money. wheres some good places that get good low results out of these heads?

 

It still should be pretty choppy with 26 degrees of overlap. Your tuner should be able to help you out with that by lowering you idle to you liking.

 

next thing im going to add to this setup is a 92/92 and a 9 inch. it pulls way harder then my ms3 setup. i break the tires loose anywhere in 1st and 2nd when my old combo i could never do that. what power do you guys think id be making with this?

 

break in the motor the right way, stay out of the throttle for the least 500 miles LOL
