I have been thinking about this time and time again. I WANT TO HCI on my fox. At the moment times are rough ![[Frown]](frown.gif)
I want to rebuild the motor, but I'm going with a budget build.
I was thinking ported GT-40 heads with upgraded springs and 1.7 roller rockers (Not sure on brand), TF stage one cam, gear drive, and possibly a holley intake if i can find one for a reasonable price.
What do you guys think? I want the TF stage one cam because I love the loping sound, but also want performance out of it. A gentlemen told me a while back that i should stay away from letter cams like E and F.
Please throw out your opinions....

By the time you port and upgrade your springs your in aluminum heads territory and they will be better than ported gt40's. some trick flows or afr's, even edelbrocks. Good choice on intake.... Why gear drive? There's a rason why no one uses that on foxes, but don't remember the reason.

Don't know, don't care, I've never had issues running timing chains. Plus gear drive is Chevy shit.

I had a "noisy" gear drive on a Chevy. The gear drive sound got old real quick.

That's a good set up I doing somthing similar myself
Ported Gt40 heads with 1.6 or 1.7 (not sure yet)
E303 cam
Still debating on intake
Just do the math as far as the heads if you are gonna spend more than 600-650 on them I rather wait

Dont do a gear drive, it will rob power over a timing chain and be annoying as fuck. When I was young and dumb I had one on my first 347. Just get a good timing chain.

I will tell you this from experience. The balance between budget and performance is not satisfying at all. Let me explain, and I'm sure other members will agree from their young and dumb days. You will be unhappy either way. 1. You will love the performance but blow your budget to shreds. 2. Stay within your budget and not see the gains you want. I'm speaking here particularly about H/C/I. Because lord knows you can get a deal on a power adder and some gears and fly in a fox. This is purely my opinion but if your goal is a nice heads cam and intake fox with good power numbers and good drivability. Save your $$$ and do it right. Don't buy parts that you will soon pull off and sell for less money to fund the right part. Rebuild your short block and bump your compression up a little. Aluminum heads are going to be your ticket. Do your research. Are you trying to stay emissions legal? Matching your components will pay dividends. Adding cubic inches is always worth something. In the end you do what makes you happy. Just wanted you to have some food for thought from those who stood in your shoes years ago.
PS. Ditch the gear drive idea. Like previously stated robs power, they wear excessively and what an annoying sound

If you aren't worried about smog then leave the motor stock and put a good turbo kit on it and it would make more power around the same price

gear drive is gay as fuck. My neighbor up the street has it on his stingray and it sounds like shit. Very loud and not cool in any way. You can always tell when a car is gear driven.

I'd recommend TF170s and a custom cam with atleast a gt40 intake and port the lower.
FYI gt40 heads are a waste of your money, time, and effort.

Holley intake will be to big for 302 especially those heads..its a mismatched combo..those heads and cam and for low end power while the intake is for top end power..
Get trick flow street heat, edelbrock rpm or ported explorer. .
Im about to run a t moss ported explorer with afr 165 heads and a comp cam xe270hr. My combo will pull hard all the way to 6000rpm

First question..how is the compression going on the motor? If everything is within acceptable levels then why don't you just nitrous the thing? Instant gratification..just make sure your timing and fuel are in check and you won't have to worry about the hci stuff until you save enough money for a real block for that stuff to go on...

All you people bitching about gears drives.
Pros. Won't break, Last forever, Sounds sick (well if you can hear them) I have a noisy set and can't really even hear them over the solid rollers valve lash.
Cons. You can only degree the cam at about 2* at a time. On cold start ups the link bar gear slaps the timing chain cover.

I am worried about smog or i would. Around where i live cops pull you over to check for carb eo numbers on aftermarket parts and if you dont have it they give you a fix it ticket. ALL BECAUSE OF STUPID HONDA LOVERS!!! ![[Mad]](mad.gif)

Fiji and Ed what robs the engine of the power the most? I know the heads play a good role, but does the intake do it as well?
