Looking for advice Long story.

It's a 373 gear I'm sure that's the N20 gear of choice in most applications

So if you're wanting to drive it a speed and distance,...I would no doubt sell trans and go to a 4l80

 

Only issue you could run into is lugging that cam down in overdrive but a non lock up converter can ease that

 

I've made my mind up to sell it as a combo once i dyno it. It's a pretty cool setup for the right person. Hopefully it'll find a home.

 

It will sell,..lots of guys needing engines and aftermarket support and year + build times will promote a sale,..I'm about to be selling a complete 494 myself

 

So there's no markings, no way to tell if the intake is SP1 or SP2. However. See the pictures. It looks like a way to mount a factory choke on the intake. I'm not sure but what else could that be? So I wouldn't think that mount would be on a SP2. Am I wrong?

 

My sp2 has a spot for a choke???? Never understood why but it does.

Mine is double drilled for both 4500 and 4150 pattern.....my sp1 for 4150 wasnt

 

My and my buddy looked as much as possible. Used mirrors.
I could send pictures but what's the point. Could not find any markings yet. I'll try again. Understand. This was after breaking ass trying to rewire a lot of crap. Removed the retarder box. Replaced the old 6a box with a 6al2 box. Seriously bad wiring under the dash. Cleaned up somewhat. It ain't easy getting under dashes over 60 yo. Lol. Anyhow we screwed around with a few other things. Bottom line. All we could tell was it looked like what I said. Trust me. We busted our ass.

 

Well you just answered my question. I am shocked that a SP2 would have that. Thx.

 

Driver side Larry ?

 

Either side

 

Here's one picture. I'll try again tomorrow. Thx

 

I cant see from your pictures but it appears on the sp1 intakethe top of the runner is level with the intake section between the runners where on the sp2 the runners ate raised making a drop down

 

Bottom line. If you buy a hot rod or any car that's been tampered with electrical wise. Have it checked out by someone reliable. This hot rod was a fire waiting to happen.

 

Here's some more pictures of the intake. If anyone can tell me by there pictures if this intake is a SP1 . I would appreciate it.

 

I would just pull the intake ,....be easier to plug the nitrous port holes and then you'll know what heads are on it

 

Hell it may have stage 3 heads,..easy to identify them,..they will offset rockers

 

The casting # under the valve cover may tell the story as to what they are also,.. can't remember if there's a correlation or not

 

Very interesting observation. I will check it out thx.
