The HiPoTek 53mm throttle body is recommended for highly modified Dodge 5.9 or 390/408 stroker with higher performance camshaft, ported big valve heads, performance intake…or with boost. Really produces great midrange and high rpm power. No problem with lower rpm torque providing your combination is set up correctly with gear and stall convertor. A great racing throttle body.
Note:
This is a precision throttle body machined on a mill and lathe, which provides true and identical matching bores, that can’t be obtained modifying the throttle body by hand, or partially by hand and partially by machine. It has smooth bores; custom machined (not OEM stamped) T6061 aluminum throttle plates; milled throttle plate shaft for increased air flow and strength, and to prevent flexing or possible breakage under boost applications; and, stainless steel low profile button head throttle plate screws. Bad and worn bearings are replaced with new sealed bearings.
The Throttle Body Core Charge Options: (71621):
You can ship your throttle body to HiPoTek for modifications or buy a unit outright plus the core charge. If you later send me your throttle body (identical to what you bought in good, usable, unmodified condition, without damage, and with all sensors and brackets removed) I will refund the core charge once I have received your core and am assured it is usable, unmodified, and without damage. I will check the condition right away and issue an immediate refund if it fits the criteria mentioned above. I will not pay the return shipping if the core does not meet this criterion. Acceptable cores must be returned within 30 days of the delivery date to be eligible for the core charge refund. You must also obtain an RMA number from HiPoTek in order to return the core.
There is an approximate lead time of 2-3 weeks.
