I'm sure you are going to get a bunch of different answers. An S-trim should be able to make 600rwhp on a 363. I would definitely get an 8" crank pulley. I would also recommend meth injection.

 

I say..Better to slow down & talk to a Pro(or three)who does this all the time? Pick their brain & let them pick your parts,even if you have to pay them. Most of us GUESS at what parts will work together,then get disappointed(myself included in that)..then have to buy more parts..more frustration! As far as the S-trim,it'll do what you're wanting..but leave little/no room for growth. There are tons of EFI tuning options nowadays..and frankly,unless you are very computer savvy..along with knowing how to tune a blown, EFI motor..I'd say most are a PITA! I don't normally endorse products...but having seen 2 cars built recently with a Holley Dominator EFI system,I say to save your money & go with the Holley system(since you are starting from scratch). It makes tuning EASY,and self learns..plus has TONS of other capabilities. If you decide to just go N/A...I think you are probably going to end up around 500rwhp. I say that because you stated that you want a trouble free,jump in & go,fun street car. To go past that will likely take lots of cam,compression,E85,and steep gears to turn lots of RPM's(not sounding like what you want,IMO).If you did decide to stay N/A...a carbureted set up will be easier,and cheaper..just gets less mpg. Read all you can about Shifter & Slo5oh's cars..they run good & are well sorted 363's:salute:

 

What is your budget? Do you want Efi or do you want to stay carb?

Is the rest of the car ready for the new hp? Clutch, drive shaft, radiator, ignition, reareand, tires, etc

 

I don't have a budget

I sold my Blow thru carb I am dead set on going EFI, I have a mcloed RST twin disk and a tko600 sitting in the car right now. I have a griffen alum radiator I bought about 5 years ago I got the biggest they had at the time for a foxbody drop in from stock. I have plans to build a 8.8 with 9" ends strange axels with a Detroit locker..thats coming next.

I need to buy ecu and wiring harness

 

I have a R331ci stroker that had a S-trim HD race blower running 18lbs and put down 680rwhp on C16 and a Lentech 3 speed, Vic Jr 220cc ported race heads, extrude honed and race ported Saleen intake and 11.5:1 Ross dome pistons. tuned on a stock computer. was in my 88 coupe drag car.

decided to swap race engines and put the R356ci stroker with Vic Glidden 300cc race heads and GRP aluminum rods in the 88 drag coupe with the YSi blower.

The R331 came out and is going 4.125 bore with CP 2618 forged dish pistons. same Vic Jr heads that have been gone thru and ported again and refreshed. using the same intake, have RCI big tube headers 1 7/8' with 3 1/2" collector with marman clamps, mcleod twin disc and a T56. using the same S-tim from the drag car pullied for 15lbs and this will allow me run pump gas on the street. all goin in the 89 road race coupe. only looking for 600-650rwhp.

u will need around $2k just for ur fuel system to feed ur beast. then suspension mods, like welded battle boxes, 31 spline axles, auburn pro posi, etc.

I run heavily ported AFR 205's that flow 330/240cfm @ .600 lift on my 11:1 CR NA 347.

IMO, I would go to the AFR 220cc head or the TFS HP 225cc head for a blown 363. I would also go to a Scat 4340 H-beam rod with ARP 2000 rod bolts, and use ARP head and main studs. I would choose Diamond or CP 2618 pistons with tool steel wrist pins, rotator neutral balanced. Nothing wrong with weisco, I just like buying top shelf race stuff. Make sure the intake manifold flows more cfm than the heads and run the s-trim at 15lbs.Look at the Vic EFi and super vic.

to put into perspective for u, I have driven my NA 347 coupe now for 3 years and drive my blown 2006 GTO and switch off between them. the blown 2006 GTO is way more fun to drive because the power is instant. 500rwtq at 3000rpm.

 

What year is your car?

 

If I where you I would get a hold of ED at FTI. He can help you out with and you can get directly from him set up ready to go is heads, cam, and intake. This will take all the guess work out of.

Your fuel pump is too small. If you are going to stay with a intake pump I would get a 340 or bigger fuel pump.

As for ECU there are a lot of different ways to go it just depends on how much you want to spend and learn. I would look into the Pro-M-EFI.

I don't know much about the Blowers so can't help you there.

 

First find good engine builder so you won't have to do it 2 or 3 times.

Any plan on meth injection


Nice thing about the holley and few other new efi systems is you can have someone tune it remote if you don't have a good tuner near by. You can also go coil on plug and eliminate the need for a ign box.

You will need a good injector look in so FIC 1150 or fic 1650. You can buy cheaper but these idle and perform better then the rest.

You will need a new fuel pump and rails lines.
Look at behind bars race cars fuel rails


Intakes IMO use a TFS R, or ported systemax or ported rmp 1 or 2. Pick one and use it with a 75 mm tb

 

Sell all the EFI Stuff, Sell the blower kit.

Put a carb on it and spray it.

 

This.

Easy and inexpensive.

(I assume you want to save some cash if you're talking On3)

 

well after a few long discussions with some friends they have talked me into going turbo and selling my vortech V1 s trim set up.

0n3 is what they all suggest going with a 76mm turbo


My callies compstar crank showed up Friday.

 

Yeah i'm not familiar with all the different turbo kits. A lot of people seem to recommend the on3 kits

I found a kit from quick time turbo which to me seems like a better quality
Base Turbo Kits

thoughts?

 

Consider B&G & Hellion...
