470+ hp goal
custom cam,fast 92 with ptm 92mm tb,ud pulley,hooker lt's magnaflow exhaust yella terras
this combo still had alot left in it,i got a little too Conservative with the cam because of idle and ptv clearance.
EDIT:that was with the stock maf too.
The tfs heads or the prc 215 heads are really hands down your best bet for making anywhere near the power goals your looking at. I can tell you that for a fact. The afr heads are nice, but they're nowhere near the power output your trying to get to. I sell all three sets of heads everyday & i can tell you i've personally installed all 3 next to each other on a engine dyno back to back. The tfs & prc 215 heads are both a healthy bit more hp over the afr cylinder heads.
The advantage the prc head has over the others is the smaller chambers without running into p/v clearance. We can ship you a 59cc head that will clear even the larger camshafts while the competitors cylinder heads will run out of p/v clearance somewhere in the 62cc chamber area...
We're also testing a brand new bigger runner ls1 cylinder head for stock bores. You'll still be able to get smaller chambers, but the slightly larger valve will give you less p/v clearance similar to what the tfs head ships with.
This was a m6 car. Not a a4 car.
For max effort camshaft i'll put the ms4 camshaft against any competitors max effort camshaft. The across the board power output the ms4 offers has been engine dyno tested time & time again to be the best all out camshaft available for clearing stock pistons...
AFR 205 10/10
TFS 215s 10.5/10
But it will require some well thought out combination of parts and some huge amount of building time, attention to detail and hours of tuning by a real guru.
The one thing that always ammazes me is that most poeple are so infatuated with peak Hp number output, instead of thinking "I would like a combination that makes the best average power between shifts to get me moving".
And before anyone recommends anything the main question to be answered first should be "What is your budget?"
The most efficient way of reaching these high Hp numbers are FI, either Supercharging or Turbo.
The most fun on the street is definitely a Magnuson. More trq that you can shake a stick at by 2500 rpm, 6300 rpm spin limit, very streetable, looks good, sounds stellar at boost, very efficient, good gas mileage etc.. all in all... Class act.
And when the dawgs while bragging about their cams and crying from exhaust fumes come along and ask you "what are you running under dat hood bro?" nothing beats that look of respect when all you utter is "7psi
".

".Predator if I could go back in time I think I would've stopped modding my car at g5x3 cam, 78mm fast, 1 3/4 lg pros, bullets, and VaraRam CAI making 400 rwhp 380 rwtq. The car was fast, and ran nice. I would've had a lot more money in the bank or possibly that Mercedes I've had my eye on for awhile now. After round one I started thinking about chasing a number. That number was 500 rwhp. What a stupid goal. After many thousands spent and lots of fun, I wised up and decided to do a stroker. Phase II of the stroker has satisfied all the things you have mentioned Predator. Good AVG power from idle to rev limit. Stump pulling low end torque, plenty of hp to bury the speedo. Should be finding that out soon enough with a slightly taller tire or just bump up the rev limiter a few hundred rpms to hit 200+ in 5th.
So with that being said build a motor that makes the car perform well everywhere, not just up top. All topend builds mean no fun on the street. They will be slow until they get into the power band. True you can gear them, but then we are just cutting corners. Do it right the first time, saves money, and headaches. Perfect example SEE SIG
Forget the 346, do a stroker and be done !!! The MS4 & PRC 215 heads will definately make big power & have a potential to make great power without cutting the pistons. The other options we're discussing are either going to require valve reliefs, or much less compression than the PRC 215s offer.

Races are won at the track not on a dyno so I would concentrate on what you are trying to do.

Whether you're aiming for streetability, high HP #s, or track times, gotta love the power numbers they are pulling out of stock shortblock ls1's these days.
