Question for Grumpyvette!!

[Guest Fast Frog]

Grumpyvette:

 

It's decision time for me regarding an engine upgrade that I've been planning for over a yr. I'm leaning toward a sbc 400-actually a 406ci-but I'm getting conflicting reports regarding the 400 small block. Primarily, many say it has inherent cooling ploblems. What are your comments, opinions and/or experience with the 400 sbc? Can it be properly setup for good street application?

in every case I have ever seen of the 406 SBC overheating its been either the guy who built the engine forgot to drill the MANDATORY STEAM HOLES IN THE HEADS FOR USE ON A 400 CHEVY BLOCK or they used head gaskets that did not have the steam holes drilled in them, get a good set of aluminum big port heads(CANFIELD 223cc,AFR210cc,DART230cc PRO_1 )with the MANUFACTURER DRILLED STEAM HOLES for use on a 400sbc and youll be just fine! btw 400sbcs like cam LSA,s between 105-110 (ROLLERS ARE NICE BUT NOT MANDATORY) and super victor intakes with 750 carbs and 13/4" headers ALOT!

 

btw look at this

Grumpyvette!

 

Thanx much for your input! Please note, however, that I'm at 4700 feet elevation here in western Colo. With that in mind, would you change any of your head or header recipe for being at a higher elevation??

PS: I'm planning to keep my TPIS fuel inj mini-ram with the Accel DFI engine mgmt system. Any comments there?
