84' Cutlass pro touring build

[Tony1968]

I'm definitely following your build. Looks great!! You are inspiring for sure.

I know you are going LS so it may differ if you are using some special kit, but under normal circumstances, if you were running a Sbc, you need to move your motor mounts forward one hole. I circled it for you.

I appreciate the heads up... I went off the diagram Holley supplied but I will check it again... Measure twice cut once !!!! Lol

Has to be. I suppose you could put a jumper wire from the hot post of the starter to the start wire of the seliniod. So when your cable is live it also activates the seliniod. Sorry for muddying up your thread. I will quit now.

Mr Turbo Zach... no muddying anything. I appreciate the discussion. The batt wire will go directly to the start side.... No need for the solenoid at the starter at all. That's what the one in the trunk is for. Make sense ????

Needs a wipe down for sure. Amazing how much dust shows on the frame. Ugggg
No carb. Fuel injection all the way. I'm not sure I'm going to run knock sensors yet but if I do I'll fit them to the sides of the block like the newer style.
Opinions welcome on that.
Also need some insight on running battery cable
Take a look at the pics. Is it feasible to route it over the frame as shown or should I drill a hole and use grommets in the rear crossmember tucking it against the inner side of the frame notch between that and the rear spring?View attachment 119386View attachment 119387View attachment 119388

I placed some bushings on frame to get an idea of the clearance. I'm thinking hard about putting the starter solenoid in the trunk so battery cable is only hot when starting and I know I will need to run many additional wires to do this. Darn decisions.

I’m just curious did you put the rear axle in and see if it would hit your brace when the axle goes up? So when your driving and hit a pot hole and have a fat chick in the back seat?

In sure it would never go that high but just in case I did check

....have decided to give all the pieces a bit of a rub down to sand them smooth too. I noticed on that A pillar any slight imperfection showed through the wrap.

I have it mounted as high as possible and I did preliminary measurements with old rear. Picking up Strange 9 Friday morning so hopefully will have it painted and installed this weekend. I think I have watched your you tube vids which gave me ideas. thanks!

Looks like some nice upgrades. Torque, at least low end, isn't the LS motors strong suit. There is a reason people rev them up, they make their power past 4000 rpm. Of course a 2000+ stall converter helps soften the lack of low end power.

The combination of CNC ported cathedral port heads, "mild" camshaft duration, and possibly the best flowing intake manifold along with 1 and 7/8 headers and 3" exhaust, 11.3 to 1 compression.... ought to do alot for "low end" torque. Now it's not gonna punch as hard as a big block down low, but it'll be close !!!😎

It will haul *ss no doubt. Actually a ported intake may hurt low end torque. Part of why TPI and motors like the Olds 455 make big low end torque is long, small diameter intake runners. Of course it will be a massive improvement over the mighty 3.8 you had. I personally only like the Gen 5.3/8 spd combos I have drove, sure the 6.2 8 and 10 spd are even better. The 5.3/4L70E, 5.3/6 spd auto and 6L/4L80E were awful in my opinion. I am sure your 6L will be a nice improvement over stock which will help a lot and be fun to drive.

There has been much written about LS engines and their difference from older iron. What was once cast in stone about losing low end torque with larger freer flowing intakes and exhausts doesn't hold true for these new fangled LS terrors. We'll see once my butt-ometer takes the test.
Oh and btw mine is a 6.1L not a 6.0..... That .1 liter makes all the difference !!!! Lol

Took a long strange trip today. STRANGE engineering in Morton Grove IL.

Such beautiful welds !!!!!
