Considering buying a WS6 with modified engine, what do you think? I found a guy who's selling a 98 trans am WS6 with a modified engine. I'm coming from rotary engines so I'm relatively unfamiliar with pushrod V8s. Vague understanding of what these mods do but would like to get more experienced advice. Here are the specs:
The motor is an 02 ls1 block 317 heads with Lunati gold dual valve spring kit and stock valves Texas speed 7.4 pushrods Ls7 lifters C5r lingenfelter timing chain Melling high pressure oil pump Rings gapped 20 thousands Cam is 237/245 .578 .578 114lsa Msd wires 180 t-stat
Does this seem like a solid build? Did a little research myself but have come to no definite conclusion. Thanks for the help.

That's a pretty big cam, what has been done to the heads?, what intake?, What exhaust? Dyno or track #'s? Stock short block/cubes? It's worth a try if it looks like it's been put together right, it's only money, if you buy it and hate it, send it on its way.

speed engineering 1 7/8 headers with y pipe into bullet style borla xr1 muffler, no mention of intake, 317 heads is all i got. that's pretty much all the mods he's listed, sent me a video of it idling and it sounds good but what do i know. transmission is a t56 with stage 2 clutch, upgraded master cylinder.

Oil pressure hot and cold? Any engine smoke? I wonder if he would pull a rear spark plug to see if its running rich or burning oil? Does the engine run hot? A compression check would also be good but that might be asking too much.

Honestly it sounds like a turd. Way over cammed and 317 has large combustion chamber so low compression. Low compression large cam runs like stir fried ***.
I think he went a few mods too far and is unhappy with it and unloading it vs doing an other heads cam package to make it right.

I'm curious as to how far setup the car is? Is rearend swapped? Tranny built? Depending how cheap he's selling for, make a good f.i. project. Depending how much boost you want is gonna depend on the bottom end though lol.
How much does he want for it?

It sounds similar to my set-up, except I have a much smaller cam. I went with the 317 heads, because I wanted to add a supercharger further down the road. It sounds like this car was heading the same direction. If the heads were milled, then they will work just fine with an N/A set-up. That cam would be ridiculous in an N/A set-up though.
If you can get this car at a good price, and don't mind adding a supercharger, then go for it! If a supercharger is out of the question, then plan on doing a heads/cam swap ASAP.

That's a really poorly matched setup. And I don't agree it was for boost. Look at the cam, that's not a boost cam.
Looks like several random parts were thrown together and that's how it ended up. I don't think there was an actual plan there.
