Not thrilled
After getting my 355 rebuild going with my Howard cam 214/214 @50 447/447 Lift 290/290 Duration flat Tappet Hyd Cam.
I not real happy with it.
Now I wished I went with a Hyd Roller cam instead so I been thinking changing the cam out.
But which one I in CA so I need to met smog law I know lucky me.
I like to go with a Cam with more of a noitecble to choppy type idle So how much duration should I be looking for what CL and lift I willing to upgrade the valve springs if needed the Trick flow 23 super 195 heads have .480 rated lift spings in the now.
When I clayed the motor during the build I had .300 more valve the piston cleaance to go until thing would go wrong.
I dont want to go more than .600 lift with 1.5 rockers.
I dont want to spin the motor past 5800 RPM's
I running 9.5 to 1 compression and 2200 stall conveter.
I know I will need to get anouther Chip burned for the new cam also.
So what cam should I should be looking at or go custom grind if so what numbers should I get.

I running a Edelbrock hi flow base with SPL runners, 24# FIC bosch type 3 injectors
I can run up to .600 lift if needed Not saying I want to use that much of lift.
Like I said a more throaty meaner Exhaust tone that lets you know it not stock will be nice it a vett.

Lift will do that, more air in/out youll hear it in the exhaust.
Id keep the int. duration @220 or less,some claim to have used 224 and passed smog which you probably can but will take a super good tune. Gains in 4 degrees are neglible anyway.
Best thing to do is try and find some flow #s at different lifts on your heads and go from there.

You want the cam matched up to the intake and heads, not by what kind of lope it has. Actually a good cam for your combo isn't going to be very lopey. I wouldn't go past 214 intake duration @.050 if this is a 350 with a LTR set up. More duration will try to push the engine past where it can realistically make power.

Though I picked a 214 duration cam myself (for my super modified SLP setup), I've heard several times that a bit of extra intake duration helps provide some time for intake reversion to fill the cylinders. I'm not sure I'd rule out the LPE 219.

I went to the LP web site all there cam say to use a 2500 stall conveter or higher I dont want to change out the converter.
So the Comp Cam mite be the better deal for now.
Comp Cam X4270HR, Part # 12-413-8, 1500 to 5500, 220/224 @50, 474 474 lift, 111C/L
I dont have to change valve springs, it will work with my 2200 stall Conveter it has a range of 1500 to 5500 RPM's.
I have buy the cam the button new liffters and pushrods gaskets Ect it mite even work with my Chip I have now.
But I have to get a hold of the place that burned my chip.
Cam I running now.
Howards Flat Tappet 1200 to 5200 RPM's 214/214 @50 447/447 lift 111 C/L
Sounds like the next door station wagon with turbos.

I know it's not a high reving race car I want the semi racecare sound.
I know the TPI not a high rev combo so which cam should I order.
What is the liffter should I get and is this a retoro cam.

Personally, I would go with the 211/219 on a 350 LTR set up. When you go with too much duration, you will lose low end to midrange torque doing it. A 219 cam in a 350 will try to take the engine to 6000+rpm. I have used several hot cams in 350's, and they pull to 6000+rpm.

I like the specs on the LPE 213/219 cam I dont have to change the valve springs is a big plus I think this mite be the ticket.
I want to keep my 1.5 RR arms I already have.
