yup that would be me my machinst chuck did them for me. i got about 10 guys to keep posting that it cant happen and about 50 that pm'd me saying give up are heads flow the same but those 10 guys are trolls

GreenDemon

Do you have a flow chart? I'm not trolling, I'm just wondering what they flowed across the board and the port volumes?

amean94ta

no i dont they not peaky #'s either real smooth chuck spent more than 40 hrs working them. i have 2.02/ 1.60 manley race flows(you can shave off the reflexsion) some welding was done. they are surfaced to 50 cc equal combustion chambers. the afr 227 start to get me at .500 but are close under

GreenDemon

That's pretty sick dude.
How much did those cost you? If he's that good with LT1 heads I'm surprised no one on here has heard of him before.

I'd take some but 40 hrs of work by a machinist sounds like a lot of money.

i own the shop he works for me its krs machining in erie,pa. some on here know of me like taner but i stay away from the mail order work mostly local guys i do work for

I have seen 300cfm on a 95-97% max port job on the Trick Flows. High 220's on the exhuast. That's with the right cross section and volume for a 383, never seen a LT1 casting get to the right cross section for a 383 and be worth a **** on them. Most I have seen on a LT1 casting is 275cfm at .500 and up, then again claimed numbers of 280+ never make high 260's on the bench here so it's all relative. Really cfm doesn't mean **** since the min cross section on a LT1 head is so little for any motor over a 355, if you want to make more than Tq on a 383 you have to get a casting that will flow enough and not choke off the system at higher RPM.

I remember that thread too. Guess some people don't forget things with time.

well you guys are close enough stop by and we will throw a set up on the flowbench

There are plenty of guys around that have been porting SBC heads to "know what they are doing". You just have to shop. I can do basic mods and feel comfortable with it, but for all out porting I leave that to a pro.
my local machinist gets very good results on SBC heads, but he's geared more towards circle track, but a few Drag Racers use him as well.

As for the trick flows, I would love to see them make the numbers you guys are talking about. It would be a breath of fresh air to have a set of excellent flowing heads for less than 3500$!!!

SStrokerAce

Yeah when I say "knows what he's doing" I don't mean that lightly. Most of the guys you talk to who port heads on here are about 10-15cfm shy of that top number, not to mention the velocity probing and extra work that goes into making them produce power. Then again $3500 or a little less is what a setup like those heads go for!

Bret

WS Sick

That is true Stroker , You really just have to goto their shop and look over their set-up, if they don't have a good flowbench and have no idea what a velocity probe is, I'd pass on em.
