I don't know what your problem is and frankly don't care. I don't have a time slip handy, but it is 11's in the quarter. My 60ft isn't where I would like it but that is due to the tight convertor. I run a Comp solid roller part no. 12-900-9 with a Victor Jr. and a 750dp. I call it hot street, and not much hangs with it on the street.

I don't really have a problem.I just don't like to be called names.In the future see if you can articulate yourself in a different manner.

Try to articulate yourself as to not come off as one. I don't like the way you argue everyone else's point. Like I said, I know what I built, and I know how it runs. Makes it hard to see your point of going to a really much smaller head. I can't see a 180cc head doing anything for me but slowing me down. If anything, I'm running out of steam on the topend and that's not head related.

With your low stall speed the smaller heads would help you get out of the hole better.

I can see going to 200cc as I am anyway. But I seriously doubt 180cc would benefit me past the 60ft mark. A stock 350 has 170cc on the vortec engines. A healthy 383 or a mild 406 would handle a 200cc like it came stock on there. The only reason I am pulling the 215's is I need them on another stroker 400 build up. Your theory on head size will soon be seen.

WHat I had said about big heads was not so you can hook up its to move the power band up and take torque away on a limited
tire street car. If you street race down here you need to have your game on. At the track any car will hook on the street it's more of a science,Ive seen 12 second cars Slamm 10 second cars
on quite a few street races

I could do a set of Track 1s or AFRs that would give you about 100hp over what you got for $2500.00 something thatwill flow about a true 300cfm @.650 would be plenty.

i like the 200 cc head and the supercharger ideas...but thats my opinion.

When u talk about putting that tight head on there u also talk about upping compression which ups the amount of octane needed to make it run right. If he's gonna run it on the street at all he probably doesn't want to have to run 5 dollar a gallon (at least that's what it is here) race gas... Yes, race gas at octane levels over 110 is nice (as is alcohol) but you wouldn't want that on the street. It's not always about power and hooking up.

Yes you could get that stuff rolling with your tax money but could you afford 5 dollars a gallon (which would last u 1 race on the street) ?? JMO. If it were mine and i had 3500 dollars in cash money, I'd just find me a *good* lower compression head and slap a supercharger on it.

Oh how true ! I have seen this put into action many times in my years of street racing.



200cc head is the minimum on a HOT 406 small block.

I think I understand why everyone is saying run the 200 cc heads.When I buy a set of heads I order them bare.At the vary least I will do a bowl blend, some work around the valve guide area, a gasket match blended at least 1 inch into the port.The whole idea is to have a smaller port volume with higher flow numbers.Most of the time when I do the port work on the 180 cc head they end up in the 185 to 188 area.

Eric, I have a problem with this because it is a well know fact that if you port on aftermarket heads without a flow bench, you can hurt flow more than help if you're not careful. I clean up the ports a little bit where the casting flash meets the machine work. I would never recommend someone port heads without experience. Most people want to bolt-on and go, which is the best advice over home porting. Therefore, choosing a head with "out the box" performance to meet your goals is best thing.

I have been doing port work for a few years.Check out this web site.e-squared-engineering.com.This is why I know a little about head work.

You and I knowing how to clean, port, and blend heads through quite a few years experience does not mean the average guy will. I feel like if someone needs advice on choosing the right heads, camshaft, intake, and CR to make a combo work, he has no business porting heads.

BTW, separate your letters so your linky worky without me having to do this to get to it.

That is a good link. Did you notice they also recommend a 200cc head for a 350/383 up to 6000 RPM? You like to give me a hard time, then you send me to a web site to show me I'm right But that's OK I took a quick look over the Dart line and I'm about it.
