  • Will it go faster?

    if so, how much

    Ok, so I have a new engine for the Vitamin C. Freshly machine .040 440 block. New Eagle 8-bolt crank and H Beam Rods. Two new pistons (nicks in the ones they replaced) and the other six have 30 passes. New Coyles timing set, New Oil pimp gear and Bronze gear. Same cam and lifters. Max Wedge heads were machined and new guides and valves. They were pretty bad. Same Harland Sharp rockers. Put the Mopar Performance Cross Ram intake back on, but getting the Valve covers on and off with that intake is a PITA

    So I have been looking for a good STR14 for some time, as the Indy is too much for that engine. A couple years ago you couldn't swing a dead cat without hitting a dual carb STR14 for $300. Now everyone things they're STR15s and wanting stupid money $1800-$2100. I finally found one that I talked down to $1200.

    So I intend to leave the MP Cross Ram on to compare to the old engine. The 426 I first had was good for 10.6. The 440 I replaced it with was 10.9s, but watching the machinist rattle the values in the guides and seeing condition of valves I can see why it dropped off. I've got better parts and heads, so I'm hoping to be back to 10.5-10.6 - but you never know. Once I've got a baseline with that, I'll swap on the Rat Roaster, and expect better.

        I'm told the inline top for a STR14 is a different shape than the base.

          A buddy tried a MP cross ram on a 500 wedge with 750 CFM and 850 CFM carbs. It ran good but improved by 3-4 tenths in 1/4 mile performance with changing to a single 1250 dominator on a super victor 4500 flange. Picked up another tenth with a Indy mod-man and six pack top and carbs. It is street and track driven. The six pack combo made for the best drivability conditions too.
          I have not ever seen a STR-14 run so not sure what to think, but curious to hear, what you discover.
