How much I need to cut??
You need to take your own measurements, to many variables, rear end , rear suspenion travel ,engine placement with motor mounts. I'm pretty sure someone will chime in on a good way to do this, but no one can just give you a measurment to go off of.

Good luck to ya..

is anyone here running a corvette style fuel filter/regulator? If so where did you mount it? And what kind of connections did you use? Do they come with the GM quick connections? How do you convert these to AN fittings?

Ran it in my 87 and mounted it to the trunk floor above the rearend on the small angled area. Makes for a short return line and pretty easily accessible when needing to change it. Russel makes some fittings that are quick disconnect to a -6, which I also used. Some have apparently had problems with these leaking if I remember right, but can't remember what the reason for this or if the problem was ever fixed.

Mine never leaked but only got a chance to drive it for a week before someone pulled out in front of me. I'm putting together a 86 ss right now and I'm going to reuse them on this build as well though.

Hey all. Just joined the club and got myself a 25k LY6 from RetroLSX for my '88 Monte SS. Trying to be budget minded here. I'm going to keep my stage 2 200r4. Iv'e been doing some interwebz searchin and there is ALOT of info and options out there. So if I could pick the brains of you more experienced gentleman for a little more insight/direction it would be much appreciated?

So far this is the direction I'll most likely be going in...

Motor mounts: Either Dirty Dingo adjustable mounts or Moroso solid mounts (Lower
mount: 62630, Upper mount: 62515) w/ Edelbrock 6701

Longtube Headers: hedman headers

Oil Pan: Retro LSX's custom pan for $395

Rework harness: RetroLSX for $500? Tune at Speed Inc?

Accessories: KWIK kit for the ALT and PS for about $300?

Cam: L99 cam reccommended by RetroLSX

Trans: I think I need spacer P/N: 12563532

Any better options? Missing anything? Thanks!

Here's where I'm coming from. SBC 406 w/ HSR.....

Mast Motorsports offers a few other cam choices that would be an improvment over the L99 cam if you are up for it. They should be able to set you up with a calibration that works well with the cams.

Code:
Camaro & Escalade VVT Cam (L92 & L99)      Mild  220/234  .570/.588  116
L99 / L92 HO Cam                       Moderate  224/238  .578/.593  115
L99 / L92 SS Cam                       Moderate  230/237  .588/.607  111

Great info thanks! Trying to be on the cheap for now so I might just go with the L99 so I appreciate the specs.

Default Speedo?

I've got an 87 Monte Carlo SS with a stock LS1/4L60e combo out of a 2000 trans am. What are you guys doing to make the stock speedometer work? My trans is shifting way too early and hard, I want to take the car for a tune but I need the speedo to function first. I think I've heard you need to get mechanical/electronical adapters for the tailshaft and a different gear for it... is there a part number or place I can get this stuff?

Theres a guy i just got the kit from to make this work.. Was the cheapest out there as I have been searching..

That being said.. its still not cheap to retain the stock speedo..


http://www.rd-eng.com/pagetwo.html

Or.. You could go this route for 325.00..

http://www.abbott-tach.com/cablex.htm

But I needed a different tailshaft as my 4L65E from a 06 GTO didnt line up..

So for my situation..I went with the tailshaft solution to correct the fit with stock crossmember as well as the stock speedo..

If you go the route I did..

You need to give him your rear ratio and tire size and he can set you up with the right speedo gear.

His price was higher on the web page, but when I called to order it was 25.00 less (450.00 total) Plus 15.00 for shipping..

I never mentioned the web price.. I just asked how much when I called..

Ask for Doug..

Regards,

Matt

If you want to keep the stock SS speedo, get the Cable-X box made by Abbott Tach.
