cam selection

[84sscutty]

hey guys,
im stuck and need help. here goes, will the edl-2201 hydraulic roller cam work for me
specs are:
powerband 1500-6500
int. duration 234@50
exh. duration 238@50
int. lift 539@50
exh. lift 548@50
lobe sep. 112 degrees
centerline 107 degrees BTDC
centerline 117 degrees BBDC
no intake or exhaust valve lash. my engine is a .40 over 327 with flat-tops, decked block, vortec heads,
and a wc t5 transmission. im looking for around 350hp and 400hp. any help
is greatly appreciated, so thanx in advance guys.

sounds like a nice cam, check the specs on more time to make sure thats pretty good lift are you sure its not a BBC roller

i'm positive its not a BBC roller. ive checked and double checked. its a cam from a edelbrock top-end kit which has the edelbrock e -tec heads(vortec copy) suppossed to have around 435 hp an 4 inch bore sbc's. made 302, 327, and 350

what compression are you running? i'm not sure the vortecs can take that kind of lift. i know they need valve guide work to take over 480 or 490 lift, but i don't know how far it goes. and i think that cam will be good for the top end, but have very little bottom end torque.
JIC have you factored in the cost of the conversion roller lifters? (i'm assuming it's not a roller block if it's a 327)
if you go to comp cams web site you can download a free copy of their cam/dyno software.

You are right i just looked at it my self, well all i can say is make sure you follow your cam card specs, also i would invest in a cloyes 2 peice timing cover with the adjustable cam button, i have one for my retro roller set up make that end play adjustment a snap.

i have a tpi 305. my machinist said that i can use the factory roller lifters out of it, i would just have to buy the hardware to hold them in. i'm hoping that since the powerband is 1500-6500 that it will do just that. i think that all i have to do about lift is get a beehive kit. if i get it then that will allow .550 lift w/o any guide work. my compression will be around 10.5:1. also i just bought a factory 342 posi-rear-end today that im going to install a true-trac in. thanx for the info and opinions so far and thanx for info on the dyno stuff. im bout to go there now.

Ok, question time. Is this going in a 327 or TPI 305? TPI or carb? Street use or race usage? I'm building a 383 with fuel injection (SuperRam) and I'm using a Comp Cams 280 XFI with 230-236 duration @ .050" on a 113* LSA. Even with my *smaller* cam and more cubic inches than you're running, mine will have one heck of a lope to it. Here's a youtube clip of my cam in a 383 LT1: http://www.youtube.com/watch?v=FhY4bgyuMig

In either a 305 or 327, that cam you have picked out is going to idle like a beast. Not saying that's a bad thing, I just want you to realize that beforehand. With a carb you'll be okay, if you're going with TPI you WILL need a custom chip. Also, most stated cam rpm ranges are based on a 350 engine. A smaller engine like yours will up the range into the 1800 (for a 327) to possibly 2500 (for the 305) rpm's.

I'm not saying you're making a mistake on your cam. Depending on the usage, it may turn out great. At least with the manual transmission it will make it a bit more livable.

Good luck

that camaro sounds awesome. does run as good as it sounds? i was thinkin of going with tpi controlled by F.A.S.T. but its not in my budget right now so i guess i will be going with a carb on my 327. that edelbrock cam is my 1st choice but ive made a couple more choices by comp cams just in case. i wont be using it for full race or anything, just a strip toy and to show out a lil bit on the streets. i want it there in case i pull up to BILLY BAD @$$ at a red light.

I'm still stuck on this. You're machinist is telling you that you can use the factory roller lifters from the 305 in a 327? The bosses for the spider aren't in this block so there is no place to bolt it down to hold the lifters. Not to mention that(i believe) the lifter bores in a roller block are taller to accomodate(sp?) the taller roller lifter.

thats what he said. he said the factory roller lifters from a tpi 305 will work along with the retro-fit lifter kit.
