From a stock L-98 base to Accel base, all the other aftermarket bases, what is the main difference? Diameter of base runners? Length? Shape? Does anyone have close ups of their aftermarket bases? What about long ram/ short ram, are the bases different or just the plenum/runners? I've never really looked close at any of the aftermarket ones, so I'm really dumb to them! :confused:
Ok well I can give you stock TPI intake manifold vs. Accel intake manifold base pictures. The ports on the accel base are huge compared to the stock one.
Scorp,
If both of these intakes are still off, could you measure the diameter of the runners(where the runner bolt to base)as well as port dimensions(where base meets cyl. heads)? That would really help! Thanks for the great pics. :cheers:
