The Stovebolt Site Forums The Parking Lot Big Bolts Big bolt engine swap

Nice move covering the brakes first!

I have seen several small blocks installed in big bolts and in most ways its not much different than putting one in a pickup.

Do you intend to leave the existing transmission in place? If so you need a V-8 type bellhousing from a '55 to '67 V-8 truck, or '63 to '67 six. The mounts on the bellhousing are different than your '49 and you'll either need to make adapters or swap to a '54 or '55 1st 4100 crossmember.

You'll have exhaust manifold/steering interfence.

The common V-8 swap crossmember available from most the venders is probably the easiest way to mount the front of the motor.

The radiator will be further from the fan than on a stock six. You may need to deal with that if it gets too hot. If not, ignore it.

One other thing to be aware of is that your '65 motor should have early heads and does not have the front mounting holes for the alternator and other accessories.
