Trivia Question 351/302

Not wasting, just gonna' go for this deal, probably easier to find used heads later rather than trying to find a dart block set up later

Seller has responded positively and has stated "Seriously Considering this Offer" this morning
...crossing my fingers boys but if I gotta' make due till the upper parts are sourced then "All hail the mighty Dart 363 block with ported Gt40p heads" ...lol

More I think about it my milled .30 p heads(54cc) will probably have to much compression with a 363 on pump gas, anyone think so too?
