Yeah I read that in a Vizard article. Take the difference between the 2 engines in cubes and use the square root of that number as the amount to add to the smaller engines cam spec's that you know works well..

Anybody running the tsp 383? if so what pistons did you go with and what h/c/i? dyno numbers and times?
I am about to order the tsp 383 so any info would be nice. lets keep this thread going.
here is how i was going to set it up:
tsp 383 short block w/ wiseco +5cc dome pistons, wiseco steel top rings, eagle 6.125" H beam rods w/ arp 2000 rod bolts, eagle ls1 forged crank, arp main stud kit, 24x reluctor wheel
want to go with either the magic stick 3 cam or Texas Speed Torquer v.2 Cam w/ the prc spring kit and pushrod package.
Want to go with the dart ls1 heads
havn't decided on an intake and tb yet.

I've got the old ms4 in my 383 with a Ls6 intake, and it only made 430rwhp/406rwtq thru the A4. It only peeks at 5900rpm with stage 1 (297cfm/227cfm) Ls6 heads, 11.75:1, and the rest of the norm. best e.t. 11.42@119w/ 1.61 60'. at 3590 lb race weight(w/ driver). Would I benefit from a better cam or fast 90or92.

-'04 Z06 MAF
-K&N FIPK
-QTP 1 3/4 headers+QTP 3" Y-pipe

Power might've been higher if I didn't run 3.73's in a 12 bolt.
All this & the car gets 26 MPG hwy.

Yes.
Stroker motors need either bigger combustion chambers in the heads or larger valve reliefs in the pistons in order to keep the compression to pump gas levels.
The reason for that is a stroker motor has extra distance to compress the mixture over a stock stroke engine.
My engine doesn't ping with 93..But it will with 92.
It pings at idle with 89. It's on the ragged edge of needing to mix in race gas.

I run Cometic head gaskets for what that's worth.
I wish I had my cam recommendation form from Pat G..because those were the #'s that he came up with.
The truck heads required some milling after the fact in order to get them BACK to 62cc's.
Whatever bowl work was done in the porting process enlarged the CC's by either 2 or 3.
I cc'd the heads locally & had sent back to TSP to be corrected.
My cam is set up EXACTLY around those dimensions.
Did TSP build your motor?
