why low HP? and top end opinions
i recently had my car (89 gt vert)dynoed and it only made 207hp and 275 ft/lbs of torque to the tires. here are my mods: 306 with E-cam, bigger throttlebody(not sure what size, is there a way to measure?), mac CAI,65mm egr plate, hooker super-comp shorties, off road h-pipe, flowmasters w/ turndowns, ford racing clutch, rebuilt t-5, aluminum driveshaft, 3.73's. it has a new fuel pump in it and it picked up 10 hp when that was done, the injectors are new ford racing 19lb/hr, heads and intake are stock, computer is stock, why low hp? i guess the stock heads and intake are the culprits. any opinions on setups? i have a friend looking to get rid of a trick flow track heat but im thinking it would be too much airto run with the stock heads till i can afford aluminum ones. for heads i want to save up for AFR 165's so would the e-cam, 165s and track heat work well? any suggestions would be great.

RE: why low HP? and top end opinions
That's not that low... that's right about where it should be for your mod list. It's basically a 306 with full exhaust. I'm not sure what size your TB is, but you'll probably want to make sure that your MAF is larger than your TB. A tune will help release some extra ponies but with no tune and just basic exhaust on a 306 I wouldn't expect too much more.

thanks guys, it did pick up 10 hp with the pump because the old one was bad it was spitting a code. i have the dyno sheets before and after. so aany ideas on heads/intake combo? i can get the trickflow track heat on sunday($400 like new) and saturday is my graduation party and i just might make enough for heads but then ill still have to add more fuel i guess

your HP ratings are lowered from shorter gears although your 1/4 time will improve. That is odd to see only 207whp with that many mods.

I made more HP with less done to my car.

RE: why low HP? and top end opinions
so r u saying all my sh*t is miss-matched? the exhaust came on the car and i had the TB lying around and when i bolted it on i blew a headgasket and that was on a lincoln 5.0 with 17lb injectors so i said fk it n got a reman'd 306 and the guy who put it in (performance specialties in pottstown PA) had the egr plate lying aorund and i told him i wanteda cam and he said go with the E and a friend of mine sold me the CAI so i figure its time for heads and an intake. I have heard good and bad about the AFR's so any help would be appreciated. I keep reading posts that say go trick flow or go canfield but there is no fact behind these is it just a matter of personal opinion? also i was going to run a trick flow track heat because i hear good things but am i wasting my time with the E cam? if so whats a good cam to run? i appreciate the help
