.Ya , I gotta keep pluggin along and keep building up slowly ...I would want to go down and ride back up .....but that peice of iron looks like a good deal ....I found a 353 ,but I don,t know how it would bolt up to the hyd pump ..I would prolly need to move the front motor mounts back a bit ..... It wouldn,t be able to pull quite as hard as it could with a 453 , but it would still pull enough for me ...
If you dont mind looking a little farther away, there are lots or 4-53's in fish boats all you should have to change is the the exhaust manifold and a couple other little things.
