A while back I purchased a level 3 quadrajet from Mark. Off came the edelbrock 750. I immediately noticed much improved throttle response and while the edelbrock seamed to give up around 4000 rpms the quadrajet pulled easily to 5000. So yesterday I went to take the Skylark out and noticed some play in the throttle cable. I tightened up close to an inch of play. Now let me tell you it pulls like it never did before all the way to 5000 and it wanted more. It almost feels like the engine is overpowering the tranny. From a dead stop it just sets you back in the seat and keeps pulling harder and harder. I couldn't be more pleased! Thanks again Mark. Cliff
