Looking at going to big block in my 71 demon love the sound and power of the 440 just not sure if it ways out, cost? what suspension work, clearances ?
Any input from someone that has done this would be appreciated.
Cost wise it takes more money to make the same HP with a SB. Build a 500hp 440. Then build a 500hp 340. Let me know the results both monetarily and how it drives on the street.
The rest is all BS. Weight, clearance etc. All BS.
Factory suspension works with nothing more than a set of conversion mounts.
Can you build a small block that will beat a big block? Yup. Can you build a big block to beat a SB? Yup. Most of the whole beating people has a lot to do with the chassis combo working and a well tuned engine. I spank a ton of big HP cars. Mine works. Not to mention. Unless you are street racing you are bracket racing. Racing a damn clock. consistency, consistency, consistency.
What do you want? build what you want. NOTHING is CHEAP!
If I already had a 318-360SB. I'd build one. I'd probably stroke it though. If I needed an engine I would without hesitation build a big block. I like street driven cars that are fast. Much easier with a big block, especially a 440.
