I put this combo together based on Rock4451's post here 372rwhp Thread I thought it was super impressive for a bolt on 302. Life gets busy and he unfortunately never got it dialed in at the track. I happen to drag race quite a bit so I decided I would try to put one together and see how quick I can go. My previous combo was ported GT40Y's, F303+ cam = 11.86 at 114 354rwhp STD.

I got it on the dyno yesterday and the results blew me away. The TFS 190 11R's and Ed's cam picked up 60 HP at the wheels!(STD) I'll post the SAE smoothing 5 sheet since that is what Rock had posted in his thread(Uncorrected and STD numbers/sheets are in the video). I did not do any tuning, just a couple pulls and the AFR is pig rich. I'll be able to fine tune that at the track. I had looked at the plugs and put in a fresh O2 sensor before the dyno and pulled some jets and it was still rich at about 11.5 AFR across the board.

I've been to the track a few times this year before the dyno and ran a best of 11.58 at 117mph. PB 60' at 1.58. Now the goal is to get the suspension, clutch program, chassis, and me the driver as efficient as possible and see how quick we can go.

I started posting some vids on youtube just sharing the process if you're interested. I don't have the personality to carry a channel lol. Just having some fun. Not much out there for Torino content... especially SBF stick car stuff.

Add another .015" shim to the pressure plate.

Good Job!!! Too bad they don't make a 1 3/4 header for that chassis, would pick up more suspect.

These guys made the headers for a friend's Boss 302 powered Maverick.

Pretty sure they can build something for the Torino.

A guy messaged me saying my combo is mismatched and needed a 2.5" exhaust and a dual plane. I've had them and the car has never been faster than it is now lol Posting stuff on the internet gets pretty interesting.
Welcome to my world!

Surprised that one of those "BoobTube" experts hasn't told you that a camshaft over .600" lift is going to cause piston to valve issues. :LOL:

This might help the launch. Kill the bog.
Home Depot screen door closer... :LOL:

A real clutch is 1000X better than that POS.

Forgive my ignorance here:

I'm a bit confused how OP here, and Rock4451 got such amazing results out of their 302s compared to almost every other dyno result I've seen from HCI. I know that proper parts combinations plays an important role, as does tuning, but most stock bottom 302s I see struggle to crack even 300WHP. These two guys here are 70-100WHP over what I feel like is more common to see. This is all on 93 octane correct?

I also have a hard time thinking it could just be a generously reading dyno, since we have 1/4 slips to back it up. I'm just curious, as part of me is considering building my stock bottom 302 but I'm also concerned it would be a "waste of time" as I'd really only be happy with a minimum of 350+WHP.
Both have one common denominator.....
