Q
Want to build a good horsepower, good fuel economy engine for a 1978 c20 with stock 350. I don't know much and need help.
I think your information is great!! I think I'm starting to understand the compression ratio stuff better. where on my engine can I find the casting number? its all gummy and it's kinda hard to clean since it's in the engine bay(?) so an exact location would be great to try and find the number...- Quinn_Hanifan

okay, i will for sure start to look into the tune-up, that's something I've wanted to do but i don't exactly know where to start. Torque sounds like a good idea, im not sure i fully understand the smaller combustion chamber for that. Thanks! Also What exactly do you mean by RV cam? i dont...- Quinn_Hanifan

All understood, I really appreciate the help and can't wait to learn more. I have the original manual and other books so I will be sure to do more reading, and the internet is something I am for sure looking around. it's just hard to find specific answers to questions that I have. I'll be sure...- Quinn_Hanifan

Mileage probably somewhere around the 20 mpg range? she gets about 10-12 right now. if not ill just suck it up and go for more power but if I can achieve that I may do that. still thinking on it though- Quinn_Hanifan

Okay, I feel like I've heard that but wasn't sure. what about the 202 heads? I've heard different things about them but what peaked my interest is that they would just fit right on the manifold I have now. its okay if not I'm curious if that would be cheaper than Vortec head and manifold though...- Quinn_Hanifan

Okay, I dont have an rpm gauge because the truck came stock with just the big fuel gauge, duly noted on the power or mpg trade off, i feel like I want more power because i do know for sure that the late 70s has the emissions tech which makes them low horsepower and kinda sucky. is there a way I...- Quinn_Hanifan

Awesome!! thanks for responding so quickly! With the Vortec Heads would I need to make any modifications to the block or head or would it bolt on just fine? I don't have big shop kinda tools so ease of installation or modification would be the best. also curious about whether or not I would have...- Quinn_Hanifan

i need a relatively budget build but Was thinking about putting either Vortec or 2.02 headers on it and a new cam, intake manifold, carburetor, exhaust, etc. I would also love to know the other necessary things for said parts. I've been trying to do research but can't find anything for what I...- Quinn_Hanifan
