Yes
Or to ask it another way, aprox how much quicker would the high dollar shortblock run than the low budget one I described ?  |
With a "tow truck" motor? Maybe not as much quicker as you think.
Now can I make a suggestion? Seeing as you apparently have a ton of old parts and no body, either find a body that fits your parts or find a complete car. Especially if you are going to try a combo that no-one else has played with.
Put a basic short block together that won't self destruct and go to the track. A basic trans and converter and maybe not the perfect gear like you would in a Bracket car and see what it does. If it doesn't show you SOMETHING, maybe it's really not a good combo. Maybe you won't like driving a 4000-5000 LB car. If it doesn't work, get rid of the car or combo and, not a lot invested. And you can still be having fun and learning.
