I can relate to both sides of the story. I have a sweet poly motor in my 64 Belvedere 4D right outside my window as I type this. Just got home from one of the last rides of the season before I put her away. I turned 43K on the way home. She's a stock 2B with nothing but dual exhaust she she'll do 110 easy. I am also one of the polyheads that's planning a stroker too with a spare 65 poly I have and have assembled most of the parts already, thanks to Gary P. (We have to talk one of these days ole buddy). I'm also the guy who bought George's nos 361 short block to replace the '65 361 I spent 4K on at the machine shop (who shall remain nameless but is on Westminster Ave. in Providence). Oh, and I bought all the parts too, 4K was just labor. I was waiting for the recommended guy but he was busy with racing season and all his racing clients and went with #2. After break-in and dropping her in (in place of a 273 LA), went about 1000 miles and she seized; cracked block. Boy, was I pissed. No guarantee, no help, no nothing. I bought the parts and I went with someone else to break her in because they didn't have an engine dyno and plus , they were really ferd people anyway. Point of the story is you don't know who did the work, could be like mine but hopefully not. You have a nice running poly and lots of knowledgeable polyheads here and options. Bird in the hand my friend... I agree there's no replacement for displacement but in hindsight, imagine if I spent that 4K on my poly. Tom when i joined here about 4 years ago, my first 62-65 was a 1963 belvedere four door. It had a freshly rebuilt 318 poly in it, with all paper work, built by a local machine shop, and i would say they did it right. Every body remarked on how nice that motor sounded and ran. It had a factory four barrel on it. I had resevations about the 318 poly as i had never seen one, and hadnt really even heard of them, but i grew to love that engine. One copless sunday morning at the bottom of a long , fairly steep uphill grade( about3/4 mile long) I decided to see what she had. I got on it ,pedal only three-quarters to the floor and that big old boat climbed and climbed, the needle nevr stopped, it kept rising and she crested the hill at about 110 mph and i could tell she had much more in her. and that was all uphill. pretty impressive in my book. at that point the poly 318 earned my respect neal zimmerman, eugene oregon ---- Please address private mail -- mail of interest to only one person -- directly to that person.
