I am looking to buy new Heads/Cam/Intake for my 86 GT. It will be going on a 306. I have Mass Air / T-5 /3.73s. I do not want to change my rear gear now or in the future (I like my current cruise rpm). I want the car to be a cruiser that will go to the track ocassionally (4 times a year?). Driveabilty is a concern and I would like to keep half decent fuel mileage. Having said this, what is the max HP combo I can get? Also what size TB and injectors? I have around $2800 saved.

The TFS street heat kit seems to be the baseline to me. I am looking at AFM 6200 N/A kit also.

Your expert opinion is needed,
Gears

the afm kit is pretty stout, with a better cam than the tfs kit.. i would def go with that one or the high rev II with the n-51 cam, tune it cause its a wild cam, but it makes some NICE power..

With my combo i made 320 hp but the driveability isnt too great but i think if you got 165's and a little smaller cam you will be alright and still make great power, problably around 300 or a little more.

They make new pistons every day, so why worry?

The trickflow kit it where it's at in my opinion.

Thanks for all replies!!! It seems Rick knows his stuff from what I see. I think the N-51 is too much for me. I am thinking the N-41 is too much actually. I kinda like the N-412 but I dont have any opinions on it.

Thats a neat combo you have there. If this car wasn't a cruiser I would almost do that exact build up. My only issue with the 165s is future upgrades. I mean, if I added a power adder two years from now, would they work for me? Have you heard of someone using 185s with a mild cam and intake? Like say the TFS stage 1 cam and a Typhoon intake?

Thanks for your opinion,
Gears

The more I look around, it seems I keep coming back to TFS.

I maybe anal, but I really dont like the way the streat heat intake looks.

the n-41 isnt that bad at all!! the tfs kit is nice but the stage 2 is kind on the wild side, and the stage 1 is too tame, thats my reasoning for the afm kit, either way i think the afm kit is better..

well I get pretty animated about gears on here on a daily basis, because people have read in magazines that the 3.73 is the best gear for a 5.0, I personally hate the 3.73 gear, not so much the fact that it doesn't perform like a 4.10, but they have never tried a 4.10 and already say its bad.. That's what gets me!!

my opinion is buy 4.10's for a modded 5.0 Ive had a couple 5 liter cars with 4.10's and they all have gotten 24mpg easily, and cruise at 70mph at 2500rpm. and my cars would regularly beat out the lesser geared cars, I mean really that's what ya want right?

I have the holley heads/intake and Z cam, makes 325rwhp, love it, super reliable, good mpg, idles perfect, drives like a stock 5.0.........that is, until you hammer it, haha

+1 for 4.10s, if it feels kinda steep you can you get a taller tire, tire size makes a big dif.
