Is this cam a horrible choice?

**Tony71502** · 08-03-2009, 11:06 AM

The block I got has a B cam already in it. It's a fresh block and about to get thrown into the car. The heads are slightly molested e7's. Trickflow lifters, comp cams rockers and pushrods. UD Pulleys, longtubes, xpipe, catback.

Is this cam going to cause crappy driveability? Is there a more ideal cam to go into a stock long block. This motor may get an H/C/I in the future but a different cam will go in at that point. I would reuse the stock cam but at the very least I would expect the B cam to make things a bit more lively.

that cam will be fine, the b cam is not a bad choice at all imo..

For a mild H/C/I on a stock shortblock the B303 with 1.7 rockers isn't bad and would be the only alphabet cam I'd even think of running.

I'm going back to 1.6's ... unless they are 1.65's... because the 1.7's are what bent my current valves.... damn float. It's a stock longblock, btw.

But, if it will work, good. I don't feel like buying another cam.

get a valve spring upgrade while your at it...the 1.7's didnt cause your valve float, its the crappy @$$ stock springs. trickflow makes a kit

**Tony71502** · 08-03-2009, 12:56 PM

Ehh, I'm not putting the time or money into changing springs / buying new rockers for use on e7's. Yeah I know the springs were too soft, otherwise I would have grabbed a new set of 1.7's instead of the 1.6s.

Off topic question: What is the stock egr spacer/throttle body bore? If I got a 65mm egr spacer would it be different than the stock intake/throttle body? Can I just bolt the throttle body to the intake plenum?

you want that cam... nothing bigger would even be worth it.

**LX2NV** · 08-03-2009, 05:40 PM

that cam should work well. i have had excellent luck with b cams with stock and iron 40's. last time i used a b cam was in a 85gt with gt40p heads... ran 13.20's all day ! any more lift then that on stock or gt40 heads and you're wasting it's time !

**yeahloh95** · 08-03-2009, 07:05 PM

i like the e -303 it has has a furosis "sp" idle i like all the "letter" cams

There won't be any PTV clearance issues on stock heads, will there?

**mlowry1260** · 08-04-2009, 11:23 AM

Tony,

that cam should clear the stock pistons. Do yourself a favor & upgrade the stock springs, retainers & locks. You're lucky you only bent some valves. Ask me how I know...

**Tony71502** · 08-04-2009, 12:02 PM

These heads have been gone over before I got them, so IDK if the springs are stock or not. But since I'm not using 1.7 rockers how much of a difference can it make? I'm using new 1.6 Comp Cam rockers. I'm not really interested in putting any money in these heads aside from having the deck milled to make sure it's flush with the block.

I mean if it's some serious sh!t I guess I could replace the springs and hardware. Does that require a machine shop or just a valve spring compressor.

**mlowry1260** · 08-04-2009, 01:35 PM

It is serious chit Tony. You don't need high dollar valve spring for that cam. It's not a place I would recommend just any junk on either.

These may work for you. They need to be setup by a shop so the spring pressures/installed heights are correct on all valves.

Learn from others mistakes...

What was yours damaged from? PTV interference? Having a shop change springs is another couple hundred.. >_<

**White5.0** · 08-04-2009, 02:30 PM

its not a couple hundred....i got mine changed for $90

I'm running Cobra 1.7 RR's with a B cam, and GT40 irons and no PTV issues. But yes I would get some stiffer valve springs just so you don't run into any issues.
