Mercuriser power lives on

07/03/2026

I love finally getting answers to hypothetical scenarios, this was a 454 peanut port boat engine mercuriser rated 330 hp the tbi truck version were like 230hp with a set of mid 70s run of the mill oval ports and a baby hydraulic roller cam quadrajet, carb and factory low rise intake 8.5 :1 compression on 87 pump gas and mechanical fuel pump and water pump in play on this lovely 93 degree shop all that being said 470tq and 402hp makes one wonder how may gutless tbi chevys could become towing savages....

Almost forgot this months calendar page.

Paul Harsanye's 1965 impala. affectionately known as "big red" dont let this big girl fool ya, all orginal 300hp 327, 4 speed, bench seat, and a 12bolt out back. she'll get up and boogie autos are cool and consistent but nothing replicates hammering out 4 in a row from a bench seat that feels like your grandmother's couch.

April, Fast eddy as I like to call him, 1965 impala super sport original 409 car for those that know muscle car history 65 was that last year for the 409 and only available for like 3 months which makes this a pretty rare bird when ed isn't cruising coast to coast in her he's hustling street races and pool grass doesn't grow under his feet.
