Default 383 Update!

Ok, so my bottom end is just about done, after about $3400. I'm ready for my top end, I have pretty much decided on going le3 with trick flow heads, along with the intake being ported and all of the supporting bolt ons. It should yield around 11.7 to 1 compression and Lloyd had specked out a cam in the .243,.251 - .597 .603 area on a 110 lsa I believe. This will be going through an m6 and an s60 rear end. I have the following tubular k member, upper and lower a arms, tubular rear control arms, adjustable torque arm with drive shaft loop, subframe connectors. ( looking for a cage). I was looking at 42# injectors for this build, Right now I'm just looking for ideas on the electrical system of the car and the rest of the fuel system. It will eventually be hit with a 150 shot of the giggly juice so keep that in mind. I'm hoping to run into the 10s if I get my shifts down and hook etc. What do you guys think for the fuel and electric system? Thanks
Tony

I have the EFI Connections 24x LSx ignition, trunk mounted battery and dual 255 in tank fuel pumps with the Racetronics hotwire kit. Other than that the rest of your setup looks solid. What crank, rods and pistons r u running in your shortblock, all forged I hope?

I'm assuming its a 383, if so with a 243 intake duration cam you should be fine with the stock computer RPM wise, but may want to consider the 24x setup for ease of tuning.

Wouldn't it be just as easy to go with an OBD1 setup?

Tuning is comparatively difficult on all LT1 PCMs, both OBDI and II - a lot of people won't touch them anymore.

The 24x setup is easy to tune and has thousands of shops that tune them.

Their sensor is mounted on a plate that replaces the whole opti unit.

Pretty slick setup.

So just by scouting around a little online I think I will get a nice single roller timing chain. Therefore I will need, the 8 coils, the standalone harness, an lsx computer, a crank reluctor, and the cam sensor that is built into the plate? Does this seem right? Sorry I absolutely hate electrical ****..

The intake is an Edelbrock Victor EFI setup which has been modified for use on the LT1, it has an Accufab 1300cfm tb, 42# injectors and a Zex perimiter nitrous plate. So it just looks like a carb setup but it's still efi.

So I just got off the phone with Lloyd. Decent sized order, includes 21* Trickflows ported by Lloyd, .243 .251 - .597 .603 custom ground cam, ported intake, Lunati Voodoo 1.6 rockers. Currently I am looking at 42# injectors is anyone can give me input on which brands they prefer. (I had bosch 30# on my last lt build before the head gasket went) I am also looking at a set of ls7 Lifters off Summit, and a 58mm Throttle body, again if someone can point out their preferred brand on throttle body it would be appreciated! Thanks gentlemen
