After six years I'm getting my '58 chevy truck back on the road with a mild budget. I'll be running a 4 speed, Ford 9" with 4.11's and a locker.
My questions are related to the motor.
It's a 283 .60 over (3.935 bore)
Howards solid cam 244 @.50" on 108 (chose cam when i was 18... doh!)
Basically my budget will allow me a set of heads
and a new intake.
I currently have 305 heads and an old Holley contender with 600cfm carb
What would you guys think about a set of rhs 200cc 2.02/1.60 with 50cc chambers.
The cam is reccomended for 11:1 so the small chambers would put me close at 10:5 with shims... I ran before with around 9:1
The only reason I'm seriously considering this is while researching LS swap I noticed the new 4.8/5.3 heads are 200cc... so if the port design is good the heads by themselves shouldn't make a dud of an engine because they're big? Just wanting to know thoughts, i might try it anyway because i can use the heads on another set up down the road. also please don't tell me to build something bigger. I'm just doing bolt ons to what i have thanks.
