what size throttle body?

i believe a 75mm would be best but seeking extra opinions-

for a 331, ecam, TW heads, holley systemax intake. 30 lb injectors and 80 MM Pro-M MAF.

also, for that pro-m maf, ill need to get some type of cold-air unit correct? i dont plan on using the OEM rubber crap.

was looking at a BBK throttle body, are they good, or should i look elsewhere?

For the 4" one you have to drill out the inner fender hole and that was a pita! I did the polished cover because it didn't look too good under where the stock airbox was...Once the hole is drilled it's fairly easy to install...

The 3.5" piece goes in the stock hole but it's tight and you have to twist and turn and play with it to get it in...we did the cover on his car for the same reason...

i have thought about a new cam, im on the fence about it still. if i do, i would probably do a custom cam.

i have bbk shorty headers at the moment. i think they are 1 5/8" but i am not positive. i actually thought the next time i did exhaust i would do longtubes, but i dont know when that would be. would LT's be too much for my current setup?

Heads are not ported just stock twister wedge.

You have street cars making 600+ RWHP with shorty headers. Sh1t...Modo is making more than that with shorty headers.

i see. if i were to ditch my ecam, is custom the best choice? i would assume yes, but also, i have a fairly common setup, and i would think there has to be some non-custom cam aimed at this setup

they are the other company i was going to look into. so far i just browsed FTI's web site, im always hearing about Ed Curtis cams, and googling his name led me to the FTI site.

how much bigger of a cam can you generally run with TW heads? i know it depends on many factors, including pistons, RR's, heads etc. the reason i am on the fence about the cam is because i do not want to have to tear the short block apart to clearance the pistons for a bigger cam. i believe my pistons from CHP had about a 9.25:1 CR with the stock E7 heads. i have the actual order sheet around.


just wondering if there is a practical limit, or if just about every setup should be checked/clayed

accufab doesnt make them for 94/95 cars. i emailed them, and the ones for Fox cars are not compatible what would be your second choice for a TB?

I am almost positive they are identicle and Edelbrock/BBK put their name on it.
they are ok quality-wise? i know both are reputable companies, just wondering if one is better than the other. i really liked those accufab ones , only heard good things about them, and they are pretty gorgeous

cool, thanks for the input. ill hopefully order something this week. just been busy and havent done any researching lately. briefly read something a few weeks ago about people having "whistling" issues with their BBK T/B's, but wasnt sure if it was just another internet rumor.

I have one that says Edlebrock and BBK on it. Works okay but sticks a little sometimes.

its plenty big for the combo... 70mm is ~800 cfm, his lower is around ~ 265. not that cfm is everything but its not "too small"

i already ordered it earlier today. was at first going to go with the 75, but your prior post about your buddy having to dremel his intake scared me off. plus, i think one of modo's ealier posts in this thread said go with what the inlet is, no more, no less

i figured since the intake inlet is 70, a 75 wouldnt help anyways. hopefully ill still be ok with this.
