I am sure you guys have heard this question before but does anyone have any rebuilding engine tips for y-blocks. I've got a 56 that needs a rebuild and wanted to do it right. Any help would be appreciated. Matt

 

A very broad and general subject! Here goes. If you dont have a shop manual get one. Install a model 57 and later carb and distributor. Bookmark www.ford-y-block.com .

It probably is not possible to halfway rebuild a motor, so like Homespun has said several times, used or nonreconditioned parts should not go back into a rebuilt motor.

High performance cams matched to rear end gearing of 3.00 just dont work too well. In fact be sober about performance components. If your rpms never go above 4500, only consider them if there will be an increase in torque.

Dont buy pistons with less than desired compression height. The result will be lower than normal compression (Egge's is a good source). If putting in a new cam also buy new lifters. Dont buy lifters produced out of country. Try to minimize quench. Ideal for Y is .040 inches. If your heads have 1.78 inch valves they work very well to produce good torque. Going to G or 113 heads is a performance move, so you choose.

Line bore the mains and balance everything in and on the motor that goes around, including flywheel and pressure plate. It will add to your enjoyment.

With gas prices like they are, and due to go much higher, it may be wise to build the motor with mpg in mind. Pistons with thinner rings are available to reduce drag, and would be useful in squeezing out a few more miles from the tank.

A true roller timing chain set reportedly lasts longer a stays in time longer than an OEM. Degree in the cam.

Bore your motor to 3.750 bore (292 standard bore).
