David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting
I always find it interesting when people have an emotional response to any appeal to logic.
Meanwhile having an emotional response yourself. Why did you start the thread and share the yt video. You must have been really excited about it ...or is it just more of the same old chest pounding..over someone elses accomplishments none the less. Reality is... they be best for a 273 cid in the 1.78/1.5 ported form.. Best head for it actually. They be okay for a 318 in the same form ..1.78/1.50 ported.. but not for max power, that's when you use a bigger port.
Flaws..
Using the late rods over the early rods.
WASTING TIME on working either one 'aside from resize & bolts'.
Using 302 heads modified to 147cc when they could have used a bone stock magnum head @150cc blended and used the same cheap nail head LS valves..or not.
Wasting time flowing the stock carb, that info is readily available meanwhile NOT flowing the 273/318 port size 4brl intake '140s cfm' early on to get an idea of how much 318/partwise will actually be used and not keep moving the goalpost.
Wanna hear something funny though..Tony is already shitting about it..so I'm hearing through the grapevine.. about how the heads are 302 and not the older ones, the LS valves, all that. Because it's not "every guy can do it" tech, its thousands of dollars we're talking, for 80% watching. Why would anyone brag on that. Big whoop.
This became a build revolving around a crummy pair of smog heads that the guy porting them kinda seems to have just wondered off from the build. It's not just about a small port.... the small valve is a large part of that personality/velocity that people drool over. This could have been easy... stay 1.78/1.5, ported 220 cfm..use 3 diff intakes , worked stock iron 2 and 4 'for fun' then a performer '318 window'... then a street dominator '318 window'... then either do the rom port mismatch or yank the heads for a 360 port match and use it. Cam, old fast rate Hughes or do the roller 'easy power but not cheap or for everyone, even today'. 318 hp is not a challenging goal, seriously.. but it's a goal and to be able to nail it the 1st time, not over shoot it, but know and nail it within a couple hp... now that to me would tell me you actually know something. Pretty funny really...funnier is the crossroad, the one between..power or chasing swirl and gas milage. How much laminar is that showing when the toilet swirl goes negative ehh.. point is.. One road will take you to passenger cars like the ones being sold today...The other road ends at top fuel and space rockets n **** like that.
