We know
1. Your truck originally had or has a 350
We need to know
A. Is this 350 still in the truck?
B. Dose the 350 still run?
C. If you still have the 350 do you have all it’s accessories and are they still functional?
D. If the 350 dose not run is it still a good core?
We know
You have a line on a good 366 for $1500
We know need to know.
A. What comes with the 366 dose it come with accessories?
B. What type of shape is your exhaust in? Can it just be bolted right to another small block? Would it be easily altered to fit the big block or dose it all need to be replaced anyway.
C. What is the value of the 350 if you still have it? Many large trucks came with sought after motor that had such things as 4 bolt mains, steel crankshafts, high nickel content castings, and good flowing heads. You really need to know what parts you have and what condition they are in, like has the crank ever been turned, dose it need to be turned or will it polish out. I bring up the value of the 350 for two reasons 1. If you decide to go with the 366 the 350 could be good trading stock to off set the cost. 2. If you decide to go the way of a 383 stroker the block and heads could be a good starting point and if it has a steel crank the crank could be used as trading stock.
From what is known now if you have a 350 that is a good core and a good running 307 witch IMHO I don’t think you would like very much but you could use it to keep the truck on the road while you rebuilt the 350 possibly for more power and torque than it had stock or even step up and have a stroker kit put in it for that 383. But The first step to finding good options is to find out what exactly it is that you have. | | |
