Hello everyone I’m in need of help I have a 1970 350 block non ac with 6 heads I would like to build this engine up but I don’t know where to start or what to buy my goal for horsepower is 400. I’d be building the engine in stages buying parts from time to time I jus need help putting a parts list together and what needs to be down to the block and heads

 

I did a project 350 a couple of years ago. It dynoed at 417hp amd 430tq. I used the following parts;
Mahle 4.100 350 piston and ring kit
#7a heads with 2.00/1.62 valves, with bowl blend, multiangle valve job, crossovers filled, center divider welded up.
Erson TQ40 cam, 220/228@.050 on a 108lsa
Brawler 750 Vacuum secondary carb
Performer RPM intake with center divider cut.
Flowtech 1 3/4 headers

Hope this helps.

 

Did you use a stock crank
