What Dwayne said....What are your goals for the car? I guarantee you that I'll be in the 10s or damn close next year with stock castings with a car you could drive everyday/everywhere...

i plan on driving it everyday but i also wanna out run everything on the road ...

 

Uhhh yeah

 

The Trickflows can work on a stroker now I would not bolt them onto a NA stock bottom car but with a stroker the larger chamber might be benificial in helping you get the compression you want without a dished piston.

Both AI and LE have cars out there doing amazing things on ported stock castings, true race cars even not just street cars. Also no matter how fast you are there is always someone faster especially on the street. On the street from a stop my whale of a car will embarrass the vast majority of other cars BUT that is because it just hooks. Even at the strip I was ETing similar to other cars with 5+mph higher trap speeds, I would walk over over them coming out of the hole and then past the 1/8th they would start their charge sometimes even just barely passing me by the 1/4 even with much higher trap speeds. Point is pay at least as much attention to the rest of the car as you do the heads and I strongly encourage you to do a lot more reading on the heads before buying.

 

Stock ported heads can work well on a 383 with the right setup, but I think both most would agree that ported aftermarket castings defintely have more potenial. If you've only got $1200 to budget for the heads though, you'd be better off working with the stockers. You'd blow 3/4 of that budget on just aftermarket casing, only leaving $200-300 for porting and hardware - maybe another couple of hunderd if you sell your existing heads. You'd need to roughly double that head budget if you're looking to go to an aftermarket head setup, that will outperform a set of worked stockers.

 

Why is that? Just curious...

 

I run TEA stage 2 heads on mine. With a 230/236 cam it layed down about 400 WRHP and runs a 11,68@116ish.

 

I am guessing he made that statement because the Trickflows have a 64cc chamber there the stock aluminum LT1 heads are "supposed" to be 58cc though they are usuallly found to be smaller on a stock bottomend this would drop compression pretty signifigantly so Trickflows own description of them states for strokers(where you could address the compression with piston selection) or boosted applications where the compression drop might be desirable.

Combination Motorsports hold the title of fastest 94-96 b-body it uses Trickflows with a whole hell of a lot of boost like 28-30psi and ran 9.8 in Vegas imagine what it would do at sealevel.

I would agree there can be more potential in aftermarket casting BUT the stock castings have enough potential to realistically take care of the vast majority of us.

 

Yep, I asked that recently. They drop the compression too much, and you actually get nowhere. Money spent and heads on the car, no power.

Hence why they're good for turbo and supercharged cars. Brings the compression down.

 

No reason you can't have the trick flows milled though... 'cept more $$$

Who wants to be part of the majority?

 

Thats what I was thinking, Whats wrong with milling them down? I thought AFRs came with larger chambers on LTx applications too...
IMO the Trickflows would be the best bang for the buck aftermarket casting wise... Buy em bare, have them ported by LE (or whoever you prefer), add your own hardware and mill them to achieve the desired CR. Wouldn't that add up to approx the price of assembled out of the box AFRs, and out perform them too?

 

Guess it all depends on how much $$$ you want to spend and how fast you want to go...There's plenty of us on this board who run pretty damn fast with stock castings for a whole lot less money...and I'm just getting started...EWP, Kooks stepped LTs, and Bogarts may just make things interesting next season...

I see what you are getting at, I run ported stock castings myself (they flow 270 @.600) I was just expressing my opinion on the aftermarket casting subject...

 

My builder was very satisfied when he took the Trick Flows out of the box. I don't think they are good for a stock bottom end due to the combustion chamber size.....but didn't you say you are making a 383?

My compression is going to be fine in my 388 with the Trick Flows and flat top pistons. If a guy is going to work the heads for you there are ways around the compression problem. Not sure it's really much of an issue for a stroker anyway, though.
