[49-blues]

i VE HEARD ITS ALOT OF CAM FOR A 6109 BLOCK BUT NOT SO FOR A 4.1.

 

[ttypewhite]

I ran a similar cam to that last year and ran the numbers in my sig with 24psi due to a cracked header and bad valve springs.

cam

I know of a few 218-224 Hyd. roller in 231 C.I. 109 block that make good power.

 

[jpwalt1987]

not really the same cam but.....

I run a 224/224 .560 lift solid roller and it has just fine street manners and the car is a beast. No track times yet but the et streets are no match at 45mph on the street.

is your engine a stroker?

 

[jpwalt1987]

No, it is a 231. with a bad a$$ set of heads and a pt70 and a 3800 stall w/a transbrake

That was the cam I used last year. Great street manners, and the split duration cam gives a nice lope at idle (but no surging or stalling, EVER)

Is that a Comp grind with 114 lsa?

 

[Lee Thompson]

Are Comp billet rollers installed @ 110 center line.

What RPM do these cams like? Over 6000 RPM?

I spun my 231 to ~6500 with a 224/224.
You need the rest of the combination set up to work with the cam though.

what was your set up,also what were your times.

 

[John Wilde]

what was your set up,also what were your times.

-JE Pistons (light weight)
-Stock Crank and Rods (ARP Bolts Every where)
-M&A Big Heads (Big Ports)
-Stock Ported and Welded Intake with Precision Upper and 70mm TB
-PT70/P Trim with H Cover
-ATR Headers and 3inch DP with external Gate
-Precision Front Mount
-FAST SEQ, Harry Hruska, Chris Chow and Myself
-83lbs injectors with SX PUMP
-Art Carr Non Lock up 16930, 200 Tranny ~4000 stall
-3.90 Gears and 28.5 X 10.5 Firestones

This combination was great.
It would fry the slicks from a roll at 60mph.
Unfortunately when I took the car up to Sacramento and the tranny broke on the first pass. I fixed the tranny and parted the combination out.

The motor and converter went to a board member.
He went 135mph at close to 4000lbs and at high altitude.
I would have expected closer to 140 in my lighter car at sea level.

The car changed owners a couple times and has recently gone
10.6 @ 130 with ~20psi and 18* timing...
The new owner is changing combinations so it will not get tested again.

 

[John Wilde]

Your combination is very similar to mine.
You have less intercooler but more turbine...
I think the interecooler would have been an issue
except the alky can compensate.

Good luck!!!
