What would be the better cam for an L69?
Ive finally decided to tear back into the 305 in my 84 and slide a cam into it. My question is, what would be the better cam? The COMP XE262, or the Crane Compucam 2040? Mileage will suffer anyway, so thats not an issue. But as far as emissions, and power gained...what is the better choice. Im currently running a Weiand Action Plus intake manifold, 2200 converter, 3.73's, and Edelbrock TES going to the stock catback. The XE only has a 110* LSA, so I dont know how the ECM will like that. I just dont want to fight with emissions every 2 years with the XE262 if the power gained over the 2040 is minimal, if any. What does everybody think?

Not sure if the computer would like a cam with a 110 LSA. I ran a Crane 2040 Compucam in my 305 HO with the CCC computer till I got my 400. I had 3.73's and a T-5, TES headers and Weiand Action plus intake just like you, but I had a Hooker catback. Idled pretty smooth, went into closed loop and no codes - even passed emissions twice!! I noticed a big gain in power esp. in the midrange.
Engine has less than 2K on it, and sittin on a stand now...waitin to find a donor car to put it in.

Wow...that was a quick reply! Deep down, I kinda thought the 2040 wold be the choice. So the gain was significant? Its good to see someone with actual experience with this cam replying. Thanks a bunch though

If you have to pass emissions the comp cam is out. The crane 2030-2040 cam should pass.Also I know a guy who did pass with a zz4 cam and I know a guy with a gm 845 that passed as well. Get a 112 lobe seperation and a 206-214 intake dur and you should do pretty good.Some world torquer's would help too. You should be able to get 260+hp with that combo. That would make it a pretty stout emissions legal 305.Low 14s high 13s sounds like a given.

I think sitting bull used that cam in his 305 actually..?
I'd do the comp though, more lift (IIRC), would give you more HP. I think the "computer" on an L69 isn't really as finicky as a TPI computer. It's not all that bright after all.

Damn, this is gonna be a tough choice, lol. Would either cam provide a significant increase in power though? I dont really want to go through all the work of installing a new cam and valve springs if it wont be worth it. Id like to install new valve seals though, and that would be the time to do all of it.....

The xe262 will make more power.This is true but I promise you that if you live in a major metropolition county that you will never pass emissions.That is a serious cam for a 305 and will lope pretty hard.218/224 dur right? That is a big cam for a 305 as a daily driver.Where do you live and what is your emissions rules.Because where I live that cam will not pass but I live in Harris county in Houston.It will be worth 10-15hp is my guess.

Glendale.What do you need their to pass?Is that a big county where you live?Trust me I know many guess with the L69 in the monte ss cars and it will not pass with that cam on the dyno chassis emissons stations or tale pipe inspection for that matter.

OK, so L69 = Carb'd 305 & LB9 = TPI 305....? And probably different pistons, cam, and other changes too?

I live in Glendale AZ, which is a 'burb of Phoenix. The emissions standards here are pretty strict. Hell, even 1967 and newer cars have to be tested. So I dont want anything im going to have to fight with. If the 2040 will make a little less power, but be a lot more driveable and pass the sniffer...then that looks to be the choice.

Call crane and make sure it is 50 state legal cam. I am pretty sure it will pass emissions as long as your motor and computer are running right. I have seen guys with bigger cams pass but they were all running TPI and LT-1 based fuel injection so I am not sure.I know the 2031 will pass.It has a 208/214 dur 438 452 lift.Also I can't find the 2040 on the website. I think it is now the 2032 214 220 dur 452 465 lift.

AZ is no more strict than the Colorado front range. I ran a 2050 Compucam in my LG4 with the rest of the set-up currently on the 350 as described in my sig. It passed the enhanced dyno test with flying colors.
