How do I make this NA combo faster?
Looking for some advice,
I have the 1st week off in June and want to make some improvements to my 408ci stroker.
It's a 408 w/243s (62cc), TQv2 cam (232/234, .595/.598 @.050), 85mm TB w/truck intake, walbo 255, 42lb injectors, dual exhaust, chassis tuned on Mustang Dyno making 361 rwhp & 350rwtq.
So...before adding FI or nitrous (bottom end is forged), I want to improve the NA setup ...what's the 1st thing you would improve?...the intake...TB....or cam?...

Thanks everyone, OK, some quick answers...and another question...
- I haven't been to the track yet
- the heads are ported (by Gunnar at Patriot, 300cfm )
- I don't like the numbers either (these are rwhp & rwtq from a chassis Mustang dyno)..but still think they should be better
What Cam should I run?.....

intake first, the truck intake is restrictive. an ls6 intake would be better, a prof products typhoon would be good too, esp in the biggest size, a ported fast would be your best bet.

what cc are the pistons like what compression are you at right now. this will help decide what cam to get. and you need to decide if you are gonna go FI or nitrous those are way to diffrent to chose a cam that will work for both. you need a true game plan and a little more info to get some help.

Good stuff and thanks to everyone for the consultation.....for budgetary reasons, I decided to buy something inbetween (SSI BBK aluminum..) which isn't as flow happy as the FAST, but much better than my stock truck intake and 1/2 the cost of the FAST. ...and it will bolt right up to my 85mm TB. And then with my left over budget, going with a custom cam....thinkg of a 242/244 112+4 .600/.600 @.050" ...I don't have an engine calculator so this is empirical data based on all the expert responses from cam threads I've started...
The better flowing heads will have to wait....
