I was pretty pleased with the results. Dyno'd 358.6 RWHP/357.96 RWTQ, SAE. First pull made 352 with 5* of knock retard throughout the run. I zeroed out the knock retard and it made 358, but ran almost a full point leaner. Got to give props to Ion (MADZ28!) , for a pretty much dead on tune. I will probably send him the dyno sheets and datamaster logs to see if he can tweak it a hair. I must have a miss somewhere, cause it took about 4 pulls before we could get one without a misfire in it, and it was making it so I couldn't see peak power rpm, only by speed. Power peaked at 5800, not sure if thats normal, most people said it likes to rev. Torque peaked at 4700, but it did make over 300 ft/lbs from just under 2500 to almost 6200 rpms. Only sacrified about 8 hp max below 3000 rpms, from there on its making more than the stock cam. At peak hp with the cam, its 70 rwhp more than the stock! Anywho, enough rambling, hopefully going to the track Friday to see if I can back up the numbers with some good e.t.s and traps. Not sure if I'm gonna slick it up or not just yet, as its still a 10 bolt. The 335 nittos should do ok for now for some mid low 12s I hope. I think with a CSI pump and a bigger TB, I might be able to hit 370. Anyone dyno higher with this few mods?

Hooker LTs - 3" True duals - x pipe - bullets

Underdrive crank pulley
stock TB, H20pump, etc
MADZ28 Email tune

 

Awesome numbers, now lets see how that thing does at the track!

 

nice man, nice

 

awesome numbers man, wouldnt it be nice to see around 400 though


also are your heads ported any?

a4 or m6

 

he did an mn6 conversion

 

thats great are you on stock heads? I want to go with the same setup and I ran a poll basically between the 306 and the 847. Most people told me not to run the cam on stock heads but I think I will. What lifters, pushrods, and tune did you go with?

 

Thats the exact cam I am going to swap my hotcam out for... Those dyno numbers are refreshing. Thats good stuff, imagine how much those numbers will rise with ported heads and ported intake manifold

That is stock unported heads and intake. 400 would be insane, and probably very hard on stock heads. I think it would be doable though, if it was cammed to peak at 7000 or around there. Drivability is a lot better than I originally thought. I had a bad o2 sensor and it was dumping fuel, causing it to cam surge BAD. Fied that and it will cruise in 5th at 45mph with 4.10s, so I'm happy. I think thats about 1400 rpms, not sure 100%, my tach is off stupidly.

 

And i lose my highest stock head hp title by 1 fricken hp lol.

Congratulations, done on the same cam too. I have the CSI pump and a bigger TB, but i lose lots through the 12 bolt. I think 370+ is very realistic with a fine tuned tune, h20 pump and TB as long as you keep the stock rear. Nice job once again, lets see some ETs!

 

Great numbers without porting !!!

What valve springs do you have on there ?

 

Great numbers! I would also like to know about all the components of your heads. I will be doing the same thing next summer, so I want an idea of what I will be doing before hand.

Thanks

Cameron

 

Great results! Congrats!

Got me beat by about 4 HP. Must be that underdrive pulley!

 

I dynoed 355 on stock heads with a 306 cam and stock rockers...

That peak power was at 6-6200, dont remember exactly.

 

nice numbers and yes that is low rpm's for the hp to peak at...

 

That is comforting to see that much power with the stock heads, would 400rwhp be posible with ported heads? That cam will be my next mod.
