Thread: carb on lt1 help

Tweet

Unless you're building a full-out race engine, I would take the Optispark off and install the cover plate (if you can find one), then use a good HEI distributor. I believe that a camshaft that fits any roller-cam Chevy small block (87-up) will fit the LT-1. For example, I use the GMPP "Hot Cam" with 1.6 rockers in my street rod, which has a Gen 1 Fast Burn 385, and in my '93 Corvette LT-1. Check with the cam supplier first, though.

What kind of idle do you get from the GMPP "Hot Cam"?
I am looking for a rough idle. I am starting to think I should sell this LT-1 that I have and just go with the Gen 1 350,since I am not going to use the fuel inj. and the opti spark.
