if you have a 1982-1984 c4 corvette
the swap to a RENEGADE intake for the O.E.M intake,
simply because it flows significantly more air,
just the intake alone is easily worth about 20 hp, but if its matched to the correct cam and heads,
its going to be a noticeable improvement, over the results, you would potentially see with the O.E.M intake.
the originally use #624 heads are very restrictive, the original cams are no where close to ideal.
youll never get the full power potential from the RENEGADE untill you upgrade the cylinder heads and cam you use with that intake,
a commonly used and well documented combo (but certainly not your only options)
is the crane 114142
the OEM crossfire heads for 1984 are casting number 462624 76cc heads
462624 chevy head flow numbers
(these are the heads that came on the 1984 corvettes)
just a bit of info on those stock #624 head flow rates
.......intake....exhaust
.100..44..........41cfm
.200..101..........82cfm
.300.155..........125cfm
.400..182..........137cfm
.500..196..........140cfm
(THATS PATHETIC)

The 624 is a light weight version of the 882 head.,. The 624 is one of the worst that GM produced and not intended for high performance use.
every time I hear that MYTH,
( that starts out with, BUT THE 1984 MAKES GOBS OF TORQUE) I want to point out a few facts

while the dual throttle body cross fire intake design is comparatively restrictive and you'll benefit noticeably,
swapping to better heads and the renegade after market intake and a cam like a crane 114132 ,
theres always been a problem with many of these dual throttle body injection system simply being improperly adjusted and tuned,
Ive found most of the 1984 corvette pick up noticeable power through simply correctly tuning and balancing the throttle bodys
the stock engines O.E.M. power is PATHETIC compared to the corvettes true potential.
theres an easy 70-80 hp or more in upgrading the cam,heads and intake
now that might not sound impressive but its easily a 45% plus power increase
the stock engine barely exceeded 205hp and 290 ft lbs
reaching in excess of 330 hp and 350 ft lbs with correctly selected parts even retaining most of the original short block 350 is do-able,
upgrade to a higher compression 383 stroker assembly and , better heads,
intake and cam, and even retaining the dual throttle body renegade of offy intake,
400 hp plus is not that difficult
