hey i had a quick question. just how big of a v8 you think would fit in there? 350 or could it cram a 427. i know alot of other thigns would change and probably have a loss of room to fit the power steer but if makes in a pure drag car how big is big for that bay do you think?
If you are talking about a big block 427 then I think the biggest problem with that would be the extra 150 pounds of weight and over 3 inches in additional length.
The weight of a small block (305, 350 etc) seems to be working out well with my existing suspension, but an extra 150 pounds might require a completely new solution for suspension.
As it is with my small block I had to go with a short neck water pump and all the brackets and pulleys that go along with that form factor to give me enough room for a 3 inch aluminum radiator and electric fan. With the added length of a big block I think you would have to completely remove the firewall and move the motor to the rear for enough room for cooling. I had to remove a portion of my firewall to fit the transmission, but I didn't have to deal with running new brake lines and wiring which you would with a complete removal.
After I run the car at the drag strip to get a baseline for the work I have done I will likely build a 300 hp 350 sbc to drop in place of the 305. Since both motors are identical other then cubic inches it will drop right in. You can get crazy horse power out of a small block so I personally wouldn't go to the trouble of trying to shoe horn a big block into the car unless I was building it as a dedicated dragster.
