I recently grenaded my motor. I spun 2 rod bearings and also found out my lifters were eating away at my cam which was an ms3. I picked up a stock used short block to replace mine. Now my question is will a ms4 or torquer v3 clear and work properly with stock pistons, 7.4 pushrods, ls7 liftera, patriot gold springs, gm mls compressed .057, and patriot stage 2 heads (2.02, 1.57). My other block had the pistons fly cut and dopnt want to go through that again and keep my compression up at stock. I have all supporting mods except ud pulley. With the ms3 my car only made 363hp/317tq. I also want to go with a 111lsa for a lil more choppy idle as my ms3 was 112lsa.

I just rebuilt my motor and went with a MS4... I like the cam but it is a tough cam to tune..... Is your car a M6 or A4

 

Well, I talked to jason and he said the ms4 wont clear with my patriot heads with 2.02/1.57 valves but might be fine with the tr v3. So I went ahead and ordered the torquer v3 but will still check ptv clearance. My car is auto, already have a fuddle 4400 hps stall and 4.10 gear with girdle in the car.

 

i know a guy running a torquer v3 with stock heads if that helps any

 

might have to fly cut with the torquer it will be close because the clear the ls6 stage 1 heads just but a little bit

 

May also want to look into TR's TRAK cam. Very close to the V3
