I have a rebuilt 355 with approximately 28,000 miles upgrades in the motor include:
9:1 speed pro forged pistons
54cc heads with 2.02 intake
and 1.90 exhaust valves
Making the overall
compression around 10:5:1
Air gap edlebrock performer intake
Edlebrock 650cfm carburetor
465 465 lift hydraulic camshaft
Moly push rods and new
Headman headers

What kind of power am I making!!!

 

About....... three fiddy

 

 

Probably right around this ^^

 

I love these threads, right along side the "what will I run in the 1/4"

 

Help if you posted what the heads are maybe. If they are some 305 casting of something.... yeah... 300 maybe.

 

350-375

 

Thanks for the help guys I was jw it's not feeling like it at all but I think it's the tranny so I think I'm going with a 5.3 th400 swap and gonna sell the 355

 

What are the specs of the heads and cam?

 

That's all I got I bought the truck last year and he said his dad built it and this is everything he told was done but I think I'm gonna sell it very healthy motor though
