advice on engine combo

[StreetDreamsGT]

hey guys, I've been planning my setup for a while and I think i've finally figured it out, tell me wut ya think, n if u have any suggestions.

331 (Should I buy a stroker kit n use the stock block or buy a new block?)

afr 185's (port work if nessecary)

GT 40 intake, ported, or SystemaxII/Trickflow R if nessecary)

Custom Cam, probably from Ed Curtis seeing how i've heard a lot of good bout him.

1 5/8 Longtubes

2 1/2 Off Road H pipe

2 1/2 Mac flowpath mufflers

75 mm TB

Mac cold air intake

There's a chance I could get a supercharger in the future (which is why I want to make sure that the block will be able to handle all the power) that wouldn't be for a while though, and I'm not planning on going too crazy on the boost.

Think I could make high 300's maybe even break into the 400's with this combo?

Combo sounds good to me.. But I recomend getting a different block other then a ford block, specially if you plan on putting any boost through it.. spend the money and get a dart block, i know people that have cracked sportsman blocks with 18lbs of boost on them..

As for your numbers there that your guessing, are you saying you'll get those with or without a supercharger?? cuz if you have a blower on that combo engine and you get it tuned you could be well into 500rwhp without a problem

I would probably go with the 1 3/4 long tubes, pro chambers, and 3" cat back system from MAC. I am getting ready to get that on my Winsor. And do not, I repeat do not get the C&L MAF or BBK 75mm TB. I have them and they suck big time, I am also working on the AFR 205's

Ho93lx, I'm hoping to get those numbers n/a. And as for the boost I wasn't planning on going near 18 lbs. I was thinking something more in the single digits. This is more of a show car/daily driver with a trip to the track every once in a while. (until I can get a track stang built) Do you still think I should get a new block though?

Powershift, As of right now I have a set of 2 1/2 stainless steel flowpath mufflers from mac and custom tail pipes. Do you really think I need to step it up to 3" and 1 3/4" long tubes? I was planning on getting the exhaust cut out from jeggs and using that to improve the top end while. http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=102162&prmenbr=361. I noticed it says you're getting Mac long tubes, if you're stepping up from 1 5/8 to 1 3/4 i'm interested in buying your old long tubes, and have you ever had any fitment problems with them? I've heard a lot of people complain. And just so you know, I was planning on going with an accufab tb and a Pro M maf.


Do you guys think I could hit these numbers with a ported Gt 40? or do you think I should use one of the other intakes? Like the Systemax.

What size injectors should I use?

And do you guys think my setup would give me a lot of problems as a daily driver?

You could probably hit those numbers w/ a GT40, I've seen some sick combo's making insane power w/ GT40's (heads/intake)...but you've got a similar combo to what I want to build. I plan on using the Holley intake w/ the AFR 185's...blown you'll see 500+hp easy.

I actually have equals right now, not long tubes, and I plan on doing the k-member at the same time, so I shouldnt have any fitment problems. The 3" back and the 1 3/4 give you plenty of flow for your 331, not to mention a ton of room for improvment when you decide to supercharge it.

What bout naturally aspirated thou?

In N/A, id guesstimate mid 300#s, somewhere in that area. If you plan on single digit boost numbers, a new block wouldn’t be worth it. Go with 42lbs when using boost, and 36ers in N/A. The gt-40 will be fine with with either setup.

do you think i would be better off using one of the other intakes though? I've heard that the systemaxII flows really well with the afrs, better than the GT40 and I was just wondering if the GT40 would be choking my combo any.

 

[StreetDreamsGT]

The other thing is, i've heard of some peoples combos making 400+ rwhp, with a different set of heads or port work would I be able to also? Would that make make it less street worthy?

 

[TT91]

Yes the systemmax does flow better, but if your still undecided about the blower, then the gt40 intake isn’t going to be a restraint on a N/A 331. I use the Systemmax on my motor, S-trim 331, and it makes some hell-a-tous power…..But No, you wont be choking it with that intake. But Yes, you will see a slight gain in HP if you did use the Systemmax.

Well if you want to get into that area…Iv seen a N/A 331 with AFR 225s make +500 hp…..and then they added a turbo, and pushed it passed 1000hp. Do u know what im talking about?…it was the 331 turbo buildup in 5.0 magazine sometime last year..Yes you will loose a lot of streetability. If it was me, 331, afr 185s( or 205s), perfomer 2 intake, 42s, a nice custom blower cam…..and about 14psi. down the intake and call it a day.
