5.0 throttle body diameter?

switching to 1.7's are a good idea. i always wanted to do a ho conversion to the coug' but never wanted to risk not having my car if something went bad. this sounds like easy power. is there a real difference? like worth your time and money difference? you guys really got me thinkin know. if i do 1.7's with my full exhaust and H.O. intake a TB you all say 19's would still be too much?

i dont mean to hijack, its kinda related.

Yup. Leave the 14's....Upgrade the pump & Add a regulator if you want (I'd recommend it), but it won't be necessary. The 14's have been proven to support 200+ HP at stock pressure.

If you're gonna go 1.7's go full roller IMHO. You're in there anyway....

The Cobra ones are rollers made by Crane.

Other cars did come with 1.7's, but most are stamped steel. The 3.8 esshag motor that came in many of the Fox-Tbird-Cougars comes to mind... 1.72:1 ratio in stamped steel to be exact.

if i do go full roller, would the ones i posted a link of in post #19 work ok? i'm looking to spend as little as possible, cus i'd probably have to take them off when i do finally do the H.O. conversion for valve clearance. i also dont want these things failing one me either tho.

Many bad stories about the Proforms. One on this very forum. Claude posted it in reference to the Goldmember car.

The Scorpions can be had for about $250 in 1.72 in pedestal mount. Well worth the extra coin IMHO.
