I read on ST before nobody ever runs an Engine over that range,, it's stoopid

Does the person that said that suck at it?

Ohh ya...

A pull where more power anywhere from 2500-8500+ rpm would have helped. Well since ST seems to be experiencing low traffic flow or low interest flow....I'll ask.. what changes need to be made to improve power over a 6000rpm wide range? :lol: :lol: Nitrous? :D That's even wider than an EMC engine,,I...

.that's for clarifying where you've decide to take the forum. I decided to make sure Speed-Talk is the #1 Performance and Racing tech forum. Supporting the Industry is a big part of that. It's not political. It's business Would not this thread then better service that purpose if it was in the Gener...

Yep I BS some but my stuff does in fact run very right. The reason I run 305 heads is because they work for what I need them to do. I have friends that ran iron eagles on their small blocks and dart sportsmans and one buddy had a crate Blueprint 383 engine. Not any 305 heads on those but not enough...

If you hang loose I know someone doing a back to back dyno. I've done a back to back at the track. Fully 60grit, took it off and burr finished it in the trailer, put it back on. Ok, so what was the improvement on the back to back at the track? .18 and used AFR to tune it. Almost 2/10ths ,, that's i...

With a 55cc chamber you will get around 11 c/r.The first time I used 305 heads on a 350 I detonated it and hurt some pistons.I switched from 91 to av gas, no problems after that. A butt dyno is calibrated to like throttle response and low speed torque ,which is fun, but the vortecs are going to win...

Jeff has the best stories and analysis.
Just saying....

Seems like he's a bs'r like you. He can't seem to get anything to run right unless it has 305 heads on it,, that's pretty funny

What was the improvement? How much more power did it make? Just for giggles, did you see a reduction in BSFC? Did it require less jet area? TIA If you hang loose I know someone doing a back to back dyno. I've done a back to back at the track. Fully 60grit, took it off and burr finished it in the tr...

isn't this the very definition of politics? No, this is a response to a real threat to the Performance Racing Industry. The OP did not make a political statement. He just made a PSA. Exactly...it wouldn't hurt to post this as a locked topic in all the forums on speedtalk,, the more eyeballs that se...

We are sticking with the 305 turds for now. It's getting the 1.84"s because I have them. He needs to save his money for other things that will be costly, like a Ford rear , custom driveshaft, custom rad, probably an electric water pump, headers and exhaust, rims and tires. I also told him this thing...

Does anyone have stock flowz #'s for the 1.72" and 1.84" 305 heads?

Want to know what I'm up against

I ran the little 1.72- 1.50 305 heads on a 350" In a 3300lb 78 nova. The heads were off the 78 Nova 305 engine. Built this car for a buddy. He said he was getting some AFR heads but for now lets work the bugs out. I bowl ported the small valve heads and radiused backcut the valves. Smoothed the cha...

113 corvette castings are cheap. Easier to port.

What's that?

I would most are working on EMC this weekend. I am mostly done. Which means I can’t get it any better. I am disappointed with the peak power and TQ but these are the most restricted rules in all the years I’ve competed. Yes such a shame to have extreme rule restrictions, makes me think of other mot...

ok,, you asked for a comparison to see how you did. its not good. from 2500 thru 5700 you were down about 161 points compared to the olds if scored by EMC. the olds heads flowed 220/160. these same heads on an 11.4 :1 set up made 504/454 Ford 306 9 to 1 comp, thick head gaskets, 204, 204, .472, .47...
