    Ok, I have a 64 Chevy truck that orig had a 230 straight 6 with 3 on the tree tranny. I recently modified it and dropped in a 305 with a 350 turbo auto tranny. I have no idea how to modify the linkage to the carburator, since the original (made for a more centered carb location of s6)doesn't lign up. I have the original rear end in the pickup. On the highway, I can't go much faster than 60mph without feeling like the engine is gonna blow! The rpm's are running really high. Do I need a new rear end or tranny? Basically, I need some carb/transmission advice.

    Thanks, }>

    Yes, you'll need a taller rear end or a different ring and pinion kit if you want it to be a highway cruiser.

    You need to get one of the cable-type accelerator kits to make things work for the carb. Anything is possible with the cable kits and brackets--I have a 235 with a 6=8 Clifford intake and a 600 cfm Holley--living proof.

    I've also got the highway blues but picked up a higher speed posi rear end originally in a Chevelle (most recently under a '55 pickup in Minnesota) and a 3-spd syncro with overdrive to improve things a little. Hoping for the best.

    Good luck.

    You mentioned a "taller" rear end or a different ring and pinion kit. Could you give the "rear end dumb" user some more information? What, where, how?, etc, etc???? I'm new to messing with gears, etc.

    Thanks.
