I for one don't think 9 is high, however, by the same yardstick you are using, the Paxton Novi for small block Fords is set up at 7.5, which is obviously less than 9, so I suppose one could ask why there is no street charger that is set up to run 20 out of the box.

I know a guy running 40 but what does 20, 30 or 40 psi have to do with the op who sounds like he will be happy if he just gets a little over 400 hp?

He didn't ask for 600 hp nor does he seem to want 600 hp imo.

call www.coasthighperformance.com for any probe needs....get it straight from them they are basically probe and run min 42-44 lb inj's and at least a pro-m 80 mm maf, anything smaller and you'll peg the meter.........9-12 will be fine for your goal.

mjr46...... i know you mentioned the tfs 170cc heads which have Exhaust Runner Volume (cc): 66cc and Combustion Chamber Volume (cc): 61cc, but for half the money I was wondering if the FORD RACING FORD RACING GT40X CYLINDER HEADS with Combustion Chamber Volume (cc): 64cc
Intake Runner Volume (cc): 178cc
Exhaust Runner Volume (cc): 62cc
would be an exceptable option as well, here is the website im looking at: http://www.latemodelrestoration.com/...y-Assembled-17

they'll work as well BUT REMEMBER THAT 600 IS FOR 1 HEAD ONLY!!.......reason I recommended the tfs is they are well proven and components on heads are good.......however with that being said the ford racing heads will also do the job........boost and more of it often overcomes any deficiency in the heads......I'm actually going to be doing a roller cam conversion soon for a guy on an 84gt with the gt-40x aluminums soon..........the main benefit with tfs is the larger intake valves as well as the valve placement vs inline heads, however in your case both heads will hit your goal of 400 rwhp. when I built my "low boost" 12psi 306 I used these pistons and rods:

shop around iirc I got the stuff a tad cheaper elsewhere but same part numbers. Cam was custom ground for s/c and I used small eddy rpm 1.90/1.60 valves however the cc in the chambers was 60-62 cc iirc.....and put my compression around 9.3-9.5. Used standard 9333pt1 head gaskets, arp head studs as well as arp main studs...stock crank polished and stock roller block bored .030...I was very meticulous at assembly making sure all clearances were to spec as well as rings gapped for s/c application.......I'm actually running a hellfire ring, had I do it again I'd of used a good mahle ring.....I was actually only shooting for 425 rwhp and since I'm non-intercooled I run meth as a cushion and to get a more aggressive tune....to my surprise we had to shut the dyno down at 5800 and power was still climbing on the graph and power was already at 556 before it started to go lean with 42 lb inj's. So, currently the car will either have to be pullied down for less boost or revamp my whole fuel system for larger inj's larger fuel rails and sump tank.........knowing WHERE IT'S AT NOW....600 rwhp is no issue for it on low boost, however the stock block won't survive to long there the way I run stuff..lol So, my whole point is, rebuild your 302 with semi-decent stuff as I did, don't go overboard with forged cranks ect ect, just forged I beam rods and forged srs pistons as I did and keep rpm's under 6500 and it'll live for a good long time at 400-425 rwhp....but make sure the tune is on!!! I used a **** poor boost retard on my first motor and have a toasted motor with 2 bent rods to show for it. The above combo IMO is just a mild one on just one of my rides....currently debating about going with a Windsor build or a dart 363 build for another ride I have...hp goal for that??? to be determined..lol

For everyone's information Ford revised the BOS 302 blocks about 16 months ago. Ford now states they can use as much as a 3.5 inch stroker crank.
The early blocks had a problem with more than a 3.25" stroke (331)......

Doing some research on some supercharger set ups, and loveeee the sound of the Vortech V-1 Si-Trim!! I like the loud sound haha but i have a few questions with it..... how difficult will it be to run the oil line too and from that it requires? How much power are we talking with these supercharger with 10-12lbs of boost? and compare it to the flowzilla of kb or power, sound, and everything please. Thanks!!!

jessupmustang302

or is there anyway to make the kenne bell whistle a little louder??

mjr46

vortech will make more power/have more potential...oil line is easy to do, mark the spot per instructions and slowly make it bigger with punches of varying sizes until it gets close to the size of the tap needed then load the tap with grease to prevent shavings from entering pan...go slow......and that's it...install fitting after tapped with sealer and you're done...done more than one, they are not that bad to do.

jessupmustang302

alright thanks! lol these kits are a ton higher when i looked at them, but i love the sound of the v-1, but it only comes in the t-trim and thats it lol so idk really, just wanted to compare the two.... is there anyway to make the kenne bell sound louder??

mjr46

not that I know of.....the kb isn't a very popular model for the foxbody/sn 95's It's limited in the fact that iirc they don't make an intercooled set up.....however I have seen some people custom fab such a set up for their KB. So, anything can be done if time and know how is of no concern to you.
