301 engine and TH 200-4R transmission


Recommended Posts

What’s everybody’s thoughts on the 301 engine? I’m thinking about putting in a roller cam with roller rockers and lifters to make it perform like a race built engine. Kinda want to make it like GM made the engine in my chevy Silverado pickup. Also I’ve been reading up on the GM TH200-4R transmission and am wondering if it will increase my gas mileage considerably. I really like my 1978 Bonneville Brougham because it handles, rides, drives and is much more reliable than most new vehicles out there today and if I can make it better on fuel and performance that would be great
