say a longer runner intake gives you 25 ft\lbs more
TQ at WOT between 2000-3000 RPM. Ok, but unless you’re having to go to WOT just to move the car around you aren’t using max TQ in those ranges.
For a car ill trade 30 ft\lbs down low for 60 up top
anyday

Yeah it's not street but driven on the street and was built for the street. People don't understand gearing a car no matter where peak may fall. Gear the car for it. Just think and ask a question if the plastic intakes do so well any number of guys would use it in the EMC with Ls builds that avg typical street car Rpm. Cam'ing goes as such from what i've seen, a 240 - 250 duration .680 lift cam for a msd - fast intake will be more like a 230 high 220's duration 790+ lift cam for a cid intake. That's how they make tq over a lower Rpm band for those EMC engines and not a MSD i would think. Just think of what their doing and why.

I didn't have this bad *** n/a pump gas engine built to see a dyno curve from idle to 5500. As a matter of fact I can't recall ever seeing someone dyno/measure a bad *** engine below 5k. What's the point? Is it gonna drive like my DD? Hell no and I never would expect it to!

a sheet metal intake on a car properly designed to shift at 7000 is like a Honda owner throwing a fart can and those stupid *** tow hooks on his otherwise stock 175,000 mile car, you ain't fooling anyone bro

he’s right. You don’t need to spend big money on heads to make Big hp with an Ls. There’s just more trade offs and work arounds

true but the higher the gear the less street friendly I would consider it. A street friendly car shouldn't be spinning 2500 rpms at 65 mph, depending on trans choice of course. I like my t56 with 3.89 combo for that reason. Enough gear to move, but not too much that it screams when I don't want it to scream. If the OP comes back he needs to change the title to "how to derail a thread in 3 posts". This has no become, "what defines a street car"

what rear gears. I have been typing different numbers lately in the tremec gear ratio calculator experimenting recently......that comment was mostly meant for the auto guys but holds some truth to the t56 guys, I should actually say the .50 6th gear t56 guys. trade offs is obviously what needs to be decided, one of the common trade offs to the larger heads is the low end, and that's why I paid more money to make large head numbers with the benefits that come from the smaller runner.

10k?
The guy who done the heads has a Cnc program also. Brodix big spring heads as cast cost roughly $1400 (one of the best heads available besides All Pro)+ cnc = 1k to 1500 depending on work done. Buy parts wanted. That's cost from either Darin or C. Frank just for Cnc. Holley high ram Cnc work from Chris is around 400 while burring is around the same cost. I'm around or close to 7k ish with crower shaft rockers, springs-high lift, valves, and intake. Built just for my application. Ls3 heads cnc ported for under 3500 with parts and intake made for 750 lift and 7500 peak. Ported the plenum myself with advice from the guy with the 8800 rpm stock cubed ls3. Got and read every EMC battle with a low rpm as low as 6500 with some, never was a plastic intake used and the competition is about avg power not peak. A intake with more potential and correct camming for lower rpm = a better Avg?

Something close to that Che70velle. Gotta get back working after my blunder which i have a few. Always updates. Waiting on wiseco dome pistons being a off the shelf part vs custom. Just need long block assembly money.
Jake those heads are liberty castings 11 degree Ls3 heads. Under 500 bucks no cnc. Have a guy who took them and created a custom port program. Scott Foxwell. Very well known guy, sent me his data and asked me to compare his work with data i've compiled on Ls heads and test bore used. 390ish at peak.

Need to put this thing on the scales. Hoping around 1700 -1800 lbs without engine and trans. Rack and pinion added, PS removed with all ac components removed factory gas tank etc.... Alternator and vacuum pump are the only thing that will be driven. Ls3 top has been ready to go. Luv this guy having wkend fun and making gas money. I can't do it, if caught minimum for me would be over a decade for sure.

With 6th being .50 gear can be your friend.
Hammer has a nice all round combo.
