I searched on Summits site but really dont know what version I would need. Ill call tomorrow and get some help, but $50 to $90 was what i saw.

On this I need to take some measurements before I can get a part to order. Ill look for the distributor I took off and measure what they need.

Summits items list there is around $300


In contrast I called the Jegs tech tonight and got these as parts. Around $500, but that edlebrock intake did the most damage.

The engine itself was the cheapest

The other thing I am looking at is the exhaust. The headers I had on the 350 were rusty but working. Not sure if they will fit the L31. If not I'll be looking for a new set...or just buy more stock manifolds instead.

The flexplate you posted here is for a 2 piece rear seal internally balanced. You need one for a 1 piece rear main seal externally balanced.
Get the mighty-mite 12- 427. It will work for a carb, been running one for 2 years or more.
I'm not saying the 195 hp is a bad motor but the L31 Vortec is the most technically advanced sbc ever built. It has the old 195 hp motor beat in almost every category. To start with you get 100 more hp and way more torque. You can run the L31 for 300,000 miles with very little wear to the cylinders. You don't have to worry about a flat tappet cam losing a lobe. No 2 piece rear main seal to leak.
For the money you get a whole lot more with the L31.
It looks like they have more versions of.the mighty mite since I bought mine. What you want is the 12-427 4-7 psi good for 400 hp.
