He already built the Forged 346 combo & made 632rwhp from it. I think he made the right choice.

I hope you didn't waste too much time thinking up this snappy comeback.

Slow is a relative term. A 15 car is slow compared to me. I'm slow compared to a 10 second car. A ten second car is slow compared to a 8 second car. A 8 second car is slow compared to a 6 second car. It's all personal perception and personal preference.

I'm working on getting faster though. I ended up buying a LME 416. It was more then $3,900 but I get more cubes and it was built to handle big shots of N20. When it's all done I should be in the 10's easy (maybe some nines on a 200 shot). But I'll still be slow compared to the 8 second guys

As for my knowledge of drag racing lemme just say this. I found that with my Nittos 20 psi works best. I do a 5-10 second burnout depending on track temp, I leave on the third yellow cutting pretty nice reaction times, I have dead hooked several times and I have impressed Mike @ New Era with both my ET and my 60'. I feel this combo is maxed out with what's in my sig short of weight reduction. You can't ask for more then that.

No reason to be defensive.

And why wouldn't a 383 last as long as a 347?

LOL why are people still voting?

darrensls1

Because they like to vote in polls but not actually read the thread

But look at it this way. Maybe someone else who comes to the same fork in the road a year from now might see this thread in a search. Then they'll get the benifit of more votes

ChevyChad, being its 4 months later - how do you feel about your 347 decision now?

That would be me only the fork was reached 6 weeks ago yet this thread still won't die!

Camarokid, way to bring back a dead thread.

Since its back up front I'll let ya'll know what I went with. I chose the 383. Weber Racing was running a short block special and I wanted more cubes but at the same time I wanted to keep my 3.9 bore heads which I had just purchased for my 346 but never got to make a pass with. 383 stroker is really the most you can get out of an LS1 block. I'm hoping for 480 rwhp through a TH350, 8" converter, 12 bolt, 4.10 gears. I'll let ya'll know around the end of this month when I get everything put back together.

I'm thinkin he is pretty happy with it. I haven't personally heard him say not even 1 bad thing about it. I know he is happy with the numbers it put out.

I am very satisfied. I honestly think I am making more with my particular setup than what a 383 would have made using a P-1SC. Everything is on the same level here, and it is all working quite nicely. If I had to do it over again, I'd go for a 347 again. It meets all of my original goals, and even exceeded a few. I am very happy with the way it turned out

It seems that a lot of people didn't even read the original post though. This was for a forced induction setup utilizing the P-1SC procharger. If I would have been going N/A, or with a D-1SC, or F1, the decision would have been different for the shortblock I chose. I think people are just too lazy to read

Yes, they do now, but over a YEAR ago when this thread was made, it was not out yet. Way to read the thread first buddy And thanks for bringing this thread back up from the dead.

But hey- now that this thread is up again anyways, I'll update everyone on my setup. The P1 has been ditched in favor now of an F1. I am still satisfied with the 347 at this time and glad I went that way. I don't have any new dyno numbers yet, but with the F1 and the new AFR 225 heads, I'm expecting to be in the 700~750 rwhp range. It is seriously overkill for a street car, and too much power IMO. So yeah, I could have gone with bigger CI and maybe have more power with the F1 now, but seriously- whats the point if I can't even hook up at triple digit speeds with my little ol 5.7L If (when) I upgrade the engine again, I am going to do either a warhawk or LSX that way I can use the 6 bolt per cylinder heads and get more clamping force.
