If you are running 11:1 compression you need to run a pretty big cam to take advantage of it. Crane Energizer cam and lifter kits are one of the best values you will ever find, Summit has the cam and lifter kits for $99. There are several different models avaliable, I would probably run the one with .500 lift.. Yes it's pretty big but made engines with higher compression and would fit yours very good, A friend of myn is running this cam in a 355 almost like yours and it's radical. I see you are not building a daily driver so streetability isn't a huge factor.. I know guys running 14:1 race 434 small blocks on the street, hell no they arn't streetable but who cares.. For heads the Iron Eagles wouldn't be too bad at all, but if you have money some AFR 190's would be great. Edelbrock Victor Jr is probably one of the best intakes you can get for a small block chevy.. That's what I'd run.

Ok, I'm no engine building guru, but this is what I would do. Since this is really a weekend cruiser and not a track car, first thing to do is loose the spool (very important, if you ask me). With the heads, I would just go cheap. Like a good stock casting that's a little worked over. Definatly a single plane intake (what ever mfgr you want). As for the cam, leave that up to the pro's. I don't think you need to go roller, just a regular cam with hydro lifters would do. Crane or comp will take all your info and set you up with the best cam for your setup, just let em know that you want it to rump as well. With this set up, it's cheap and would make that light car move pretty good. Just add a nice loud exhaust and you'll be turning heads no problem.

Just a couple of comments/questions...why the single plane intake (2500-6000)? I think you mentioned it in a previous post, that the bottom end will suffer, and the motor will take some high RPM's to come to life. For street use, would a dual plane not be a better bet? I remember when I went to a single plane on my old coupe...the bottom end bog drove me nuts. I switched back.
I am also at a bit of a loss about running the higher octane fuels. You may end up losing power with the hi-octane slow burning fuels. I would save those for your 13/1 C/R's or when adding N2O or other power adders. Lastly ...I am jealous of someone that has 75 sponsors Alaskan, or did you mean contingency stickers on the car? And you have to have the product on the car for which you carry a sticker... Ron |

Well, I say the single because with the cam being fairly big, and the compression being on the high side, it doesn't make sense to me to have an intake that would try to perform in the lower r's when the rest of the motor won't. I see what you are saying, but like I said, I'm no guru. As for the high octane, 11:1 comp is pretty high, and it would be best to run something better than just the regular 91 (that's as high as I can get here in Sacramento).

If Chevy High Performance Mag. can make 390 horses with a XE268H cam, stock Vortec heads, and 9:5 compression you can definitely make well into the 400's with your set up. |

I know ALASKAN and he knows about sponsors, so no need to bash him for his accomplishments in life.
He has and knows what he is talking about. Enough said. George
