Anyone know about this cam and emissions.. a guy is trying to sell it to me but I am not sure it will pass emissions... 492/492 lift
112 LSA... seems a bit high.. what doy you guys think...

 

With a properly programmed PROM I don't think you'd have any problems. Lift doesn't have much effect on how dirty a cam is, it's the duration and overlap. The HotCam was designed from the get go to be an EFI preformance cam so it has minimal overlap but relativley high duration. Ask on the TPI board or ask at http://www.corvetteforum.com . That's where I ask any important questions I have concerning TPI.

I agree..It also would depend on the rest of the combo..My 220/230@.050 passed..that was with 22 lb injectors though

I to will be running 22lbs injectors..
Edelbrock intake and runner
SLP 1 5/8 headers
Stock crank
52 mm TB
I have a cam 450/460
Stock ported heads
9.0 compression

they say your suppose to match your cam to your gears, I have 3.42's so tell me what you guys think.


I was just pondering about the LT4 cam since it came up for sale
How's it Idle DAZ?

 

I'm pretty sure the LTx cams are designed with some overlap since for those engines they attempted to kill the EGR in the design. This is done with the overlap allowing some exhaust gas back into the cylinder, which is the same purpose as the EGR. As for their success, I'm not too sure what the numbers are but the design did help somewhat. If anything, it will actually help emissions I think.

 

I dont have an LT4 cam..but mine idles OK..Its a Comp Cams 08-305-8

LSA 114
220in 230 ex half lift
.510/.510 lift
hyd roller

"To work with the stock computer,higher stall TC," etc etc

My criteria for cam choosing
1)Application-street or drag or towing..etc..
2)Head flow
3)TC stall
4)weight of vehicle
5)rear gears
6)RPM range-based on intake and all the above mentioned

WHF when i asked you a dyno day YOU told me your engin was stock. with only the ram air mod. you did not say anything about a cam or ported heads!

now i see where all the extra ponys came from
if you dont want the cam PM me i will take it

 

WO WO WO WO !! This is an engine I am building a 350 I have on a engine stand at home... just trying to find out what works good..

hahahahaha
you thought it was in my car!! umm no..
That is a 305 5 speed stock heads and cam just free mods and underdrive pulleys

Soon to have 1 5/8 SLP headers though.. for testing at the next dyno run.. and maybe a custom chip if I can figure out volumetric Efficency.. VE... what a pain it is..

 

thanks that clears things up
