Rpm range??? I had a cam ground by a company in Tacoma wa. I asked for the CC503 224/230@112. What i got was 226/230@111. .540/545. I was looking at the LE 226/232@110 .578/.573. The company said they were only tooled to go .560 which is kinda weird to me. My questions are what is the rpm range for the 226/230 111 that i have in the car now? I figure it is 1900 to 6200 rpm. (i shift @6000) i know i need a 32-3600 stall. And is there any real benefit as far as tearing it down to putting in the LE 226/232? I have a set of 93 374 heads that will be sent to LE next tax time for the full port and polish if that factors into the decision? Thanks for ur input!!!

For some it is but others do it all the time. You'll have a low to mid 12 second H/C car when you should be in the 11's. It's ok to short shift, you're just not going to see the full benefit of the cam. The dyno would tell the optimal shift point, meaning the completed shift.

So to get the full benefit of this cam, do u recomend 62,63 with a completed shift of 65,66? Or 6500 staight up on the tach? Its just that since i have been recording my runs and looking at them. I see the higher rpm when i shift and i really dont know which one i should rely on or look at. Before the recording it was set the shift lite and GO!!!!

I dont have a wide band yet, just a standard autometer guage. I dont put alot of faith in it, but it reads in the stoich range at wot. Kinda lean on cruise at 60. Dyno run is 150$ for 3 pulls and the cant tune a 93. I am working on getting setup for Datamaster logging. I may even get all the burners to tune myself. Big bucks IIRC. in 2 weeks when track opens i am going to go for 6500 on the tach and see what happens. Ha ive got another stock motor.

This motor has 50k on it. It has been siting in my garage for 6 yrs. I bought the long block for 500$ it is a 96. The stock 93 motor cam out. It had 186k on it. Still runnin 13.48@105.49. So they are both strong. Gonna do LE2 on the origanal motor come tax time. I really wanna supercharge one of them. NEVER LIFT EVER!! MWAAAHAHA!!!!!!!!!!
The 50k motor should be fine but the 100k would need a rebuild Seen too many guys do H/C & Blow em up!!! My teachers from early in life always told me Take it easy on em after the head & cam upgrade on higher milage motors MY Right foot never listened & they always hand grenaded 
Live & learn @ 40 I only like doin **** once LoL
Live & learn @ 40 I only like doin **** once LoL LoL I hear ya on that My 95 is gettin Completely redone. Paint & Body plus Complete drivetrain It aint as fun as it used to be pullin motors & swappin **** in a few hours LoL My LiL ole 396 nitrous motor should be a strong runnin SOB 
Might need to go to E85 since high volume 93 octane stations are gettin harder to find & Im not payin for VP fuel Funny thing is Im buildin a Stock LT1 for an S10 ext cab at the same time Other than 6in rods & new pistons itll be pretty much all stock parts to get good milage LoL after its runnin its gettin solid axles & 35x12.50R17s Thatll be my DD

I would be interested in seeing the dyno chart for your buddies motor to see if if his 503 really requires that much RPM. That RPM really seems high and he might have better ETs by bringing it down a little assuming he is needlessly spinning it too high.

I went to the track 1 time with this combo. With a DA of 2300 i tried a few different rpm's. 62,61,59,6,6150 the best run of the day came at 6k. I couldn't really trust the mph on the slip, it was anywhere from 104 to 108. I think there was some inacurracy that day. 104 a couple times really seems to low to trust! I like the 107.91 and 110's myself. Haha There is another session on the 14th i will try again. BTW S10's with V8's are a BLAST!! i have built two B&M supercharged ones. I have played with them for a while then trade them. (no room for good stereo, headers get loosened up quick...always tightening). I traded my last one for the Trans Am i have now. Have fun!!!
