360 pros & cons vs 318

Thanks rumble so the 413 wouldnt be a good idea then.... No not stock cam i meant stock bore and stroke. I have a comp cams thumper. the smallest of the trio... 486/473 lift flat tappet. Right now i have a 3.23 sg. Was trying to find a 3.55 or 3.91 whats a better choice of rear gears? Tranny is a 904, seller said had a shift kit, (but i think he jus said it to help sell the car). It has no problem of burning the tires at all puts a grin on my face...but doesnt scare me. thanks for the replies guys, just wondering if all those mods would be better on a 360 rather than my 318, or go big block. Shortening of the driveline is not a problem neither is getting a trans for big block. What else would be a big cost factor for a 413? Thanks
