    ok, the different heads must have different port volumes and valve sizes right? Does anyone know where this info is? How many cfm does a stock port flow? i know how these things affect performance, and i am looking for background to start my first project. I am looking at B series motors. throw me a frickin bone here.

    if there is another post, post me a link! i couldnt find one.

    Cam specs

    I know that this wont help you too much but it is a start. Are you going to go vtec or non vtec?

    ok, the way this project is starting to shape up is as follows. I plan on selling my 1972 cutlass S which i have driven since i was 17. I have ported heads, big cam, headers, custom exhaust, with a 3.42 posi (LSD) rear end. It has less than 75000 original miles, and i am yet to lose a race. Victims include several SC400's, a 2001 Lightning, a supra, and a new body style corvette. I believe it is deep into the 13's with a small block, in a car weighing over 3500 lbs. In my dreams i will get $4000 for it (needs paint) so i figure my budget will be 3500 plus or minus. I have found several local civics for less than 2 grand, i want a 92, or maybe an earlier hatch, but i have heard that a GSR swap in an older car is a hassle. I plan on going with a B18, as i was NOT impressed by the guy in Pasco with the 1994 hatch sporting a JDM B16. (This guy had vtec controllers, and fuel curve thingies coming out the dash, and was considering forced induction) I plan on porting the head before the engine is installed, and eventually i want to upgrade the cams. I do not see myself boosting the car, I do plan on squeezing a small shot (50-100). I like how nitrous adds power without moving the powerband toward the top end like forced induction does. Does this sound like a good plan? Am I going to need expensive electronics to manage my project's A/F needs? I am building the engine, and testing cams on Dyno 2000, so the more information i can get about port flow, and valve sizes the more accurate the testing will be.

    Administrators? Does ANYONE know the specs i'm looking for?

    I think he wants a little more precision than that!

    That specs page on Mr. Bone's site looks pretty good... and he's a pretty reputable source of information. I don't know the head specs, but at the very least- that's a good start.

    You could try contacting some place like Gude or Dan Paramore,who do head work and ask them.Jean at unorthodox had alot of info on head specs to when I spoke with him.I've checked the websites and couldn't find any thing but if you e-mail or call them I'm sure they would share that with you.
