I know this will start some interesting differences! I am sure some will say the 195 stocker that came with it & some will say a overdriven 6-71 blower with huge cam. My vote goes to a 10 to 1 compression rebuild with forged crank, aftermarket rods, super mild solid roller with AFR or Profiler heads, dual plane intake & a Quadrajet. So lets hear your choices! It's rainy here & I'm bored.

IMHO the ultimate cure for the common 350 is to replace it with a NOM 427. At least, that's what I ended up doing.
Could use some of that rain here; 109* index today.

The other one is a future project that I built a Dart SHP 4.125" x 3.875" 414 Cube short block. I bought a chassis with a "VB&P PERFORMANCE PLUS SYSTEM FULL KIT" & C-5 Brake Conversion. I am thinking of giving it a Baldwin Motion type paint job. A bigger project!

I figure, if I was going to do a big street BBC C3, I would do a aftermarket block with big bore & short stroke. I think when you get into BBC C3 territory, you have to start thinking about injection merely for clearance!

My 190 hp L48 was good enough for about 1 day... I installed a K&N filter first thing in '97 and am still personalizing the performance to suite my evolving tastes.

I found some info in various books and sites around that web that says the Tri-Y design is better up to about 5500 RPM or so and that a 4 into 1 design produces more horsepower at the top end. Bottom line was that if you are racing, you need the 4 into 1. If you're primarily street driving the Tri-Y is better. Stan of Stan's Headers told me the same thing. Problem is that Stan's is the only manufacturer I could find for Tri-Y's for our C3s and they only work with straight plug heads. Mine are angled so I either have to drive 1800 miles (1 way) to have Stan build a custom set or I have to change heads.

I will build a blower engine soon but I don't have the heart to cut up my vette hood so I say go for the cubes and torque is always more fun than horsepower on the street

I want decent performance with acceptable gas mileage. I do understand that cars today have better efficiency & that gear/transmission ratios have changed. It's very unusual today to have a car without some kind of Overdrive. In suburban traffic, someone is always trying to race you from a redlight, be it a soccer mom in a SUV or a black smoking diesel 4x4.

70's LT1 is what I meant.
