Head selection help

[BLOWN347STROKER]

I am in the process of building a 351w based 427 stroker motor. Now I have eagle h beam rods, probe forged pistons set up for trick flow heads. This motor will have a D1SC procharger on it as well so it will be seeing boost. Should I stick with the trick flow heads that I have or should I sell them and get a different set. I have a set of trick flow twisted wedge track heat heads. Would like to use trick flow heads since the pistons are dished for them and I don't really want to swap out pistons here is the info on the heads.

Let me know if you guys think these heads will work fine or what heads you think I should run.

those heads would be awesome on a 302, so would that D1.

Go with AT LEAST a 225cc cnc ported trick flow Hi-port. and start looking at F-series prochargers.

 

[1991notchbackLX]

+1, that D series is going to be undersized for the cubes and power goal you have

 

[fiveohwblow]

Did I miss what your power goals were?

 

[1991notchbackLX]

I assumed his power goals for a 427W on boost were lofty. More lofty than 302 heads and a D series procharger could accomodate.

 

[fiveohwblow]

post said power goals for us to give proper help

Meh.. I'll go against the grain and say keep your heads. Send them to fox lake.

I do like the idea of getting them ported and polished but the problem with that is for not much more I can ge a new set of heads. I would like to be pushing 650-700hp to the wheels. I already have the D1SC procharger so that is what I am going to be sticking with for now. I don't think my power goals are that far out of line. Want to run the quarter in the low 10s if not faster.

You did look at the flow numbers on the ported heads, right?

I do know there is more to life than flow numbers, and this is another reason I'd have fox lake do them. Just my opinion.
Also, I'd check out what TEA can do for you.

I have been thinking about doing it both ways. I would like to get them ported and polished but that does run alot of money. If I do the heads then I have to do the intake too to maximize the power for the intake. Haven't decided if I just want to shell out the money to do it or if I just want to buy new heads and sell the sets I have now.

As far as I can tell, it's cheaper to port the heads than replace them. Odds are, you would get more power porting than replacing them too.

Do you already have an intake for a 302? If so, regardless, you will have to buy a new lower. And for the same reason you would port the heads, you should port the intake even if you replace the heads.

What intake do you plan on using? Something like this, you prob could get away with just port matching the lower.

That is the intake I was thinking about going with but Not for sure what I am going to do yet.

highports ,brodix neals, or SC1's

also im with everyone else that D series is a lil small... but i can see the i have it im gunna use it idea.


also search NOVI357 on google... hes running a 427 with an F3 in a coupe with a 4r70 with 17x10 FR500s and MT radials running mid 8

 

[rbonella]

TFS High port heads would work very well as mentioned above

 

[90lxcoupe]

Either way is a good option with the heads.

You could sell your heads for a good 800 bucks and use that towards the purchase of the new heads or put money into your heads.

A well build 427 stroker should go deeeeeep into the 10's N/A without trying. I think that you should really rethink what your goals are with the car, when i hear 427 and boost in the same sentance if your not going low 9's there is a problem, there is a guy on corral running 8's with a 427, F2, and a 17'' tire.

You could sell the blower, run the motor N/A and use the money from the D1 to fund stroker motor parts, and it will easily exceed your goals

 

[BLOWN347STROKER]

The only problem with the high ports is then I have to get a custom set of headers made to fit. Anyone know how much those cost. Will my springs and retainers just switch over from my twisted wedge heads to the high port heads or will I need a new set.

novi357.... thats a BAD ASS car...

your right about the F2.. thought he went F3 when he went to the air to water setup...

first time i saw him driving the car on the street we were waiting outside MIR to meet up with the other car pitting with us and he came by and MY GOD its unreal how bad ass it sounds coming down the road. guy who owns the race car didnt believe it it runs mid 8's how he drives it on the street

 

[BLOWN347STROKER]

Ok Heres the deal. I already have the parts for the short block. I have the crank, rods, and pistions, Now i want to keep the blower. So I am going to use the D1sc for now. I talked to procharger. They said I will only be pushing around 12lbs of boost with the D1SC on that motor with the renegade setup. I am fine with that. I am wanting to figure out what to do with the top end.
So far I have two sets of trick flow twisted wedge heads as mentioned above. I have two motors that I am selling the parts I don't need and trying to pay for the new ones for the car. I don't really want to go with the high ports because of the cost of custom headers. Now since I am going with a different bracket setup maybe I could sell my bracket and procharger to get close to a F1 and just buy my new brackets for the f1. Don't know what you guys think. I would like to stay with trick flow heads but I don't want to spend 2800 on a nice set of r series. I might just sell the extra set I have to help fund porting and polishing mine as mentioned above.

 

[srtthis]

check yellow bullet and the NMRA fourms i bet you can find a set of used highports and headers pretty cheap

 

[BLOWN347STROKER]

The reason I want to stay with the D1sc right now is I am not looking for rediculous power. I know that it won't have a problem making lots of power anyways but I have a stock block with a girdle and an iron crank. It should hold up fine. But I don't really want to push it with an f1. Plus I just got off the phone with procharge and they said my D1sc head unit would cost 3000 new and an f1 would cost 3500 new. Now Im no genius but when I can buy the whole kit off of ebay for 1500 for a mustang I would not spend 2500 just on a head unit. So I will never be able to sell my parts and get the money for an f1. Just sticking with the bottom end I have and the D1sc I am just looking for some help on the top end parts.
