I've been a member of some FE forums for years. I've always wanted to build a stroker 427 with Tunnelport heads. I've never seen a true high effort TP build posted. Maybe I missed it but I haven't seen anything with TP heads that screamed.
Most of you have seen Jays post about dyno days at his house with the 498 Blair built for me. It tells a story but not the whole story.
Three years ago I found a nice set of heads and intake that I bought from Rich Mastro. I found a nice used Pond Block. A couple years ago I found Blair Patrick a true gentleman and a savant with the FE.
I had several restrictions with my TP build. Like his stock class 352 that Jay posted and performed really well for what it is, Blair got stuck with many roadblocks to building max hp on my build.
My TP build does not represent a max effort TP from Blair. It was build first with durability in mind. I wanted several things and some of these "goals" fight against each other. I am building a street legal road racer. Yea than makes sense right?
http://www.lateral-g.net/forums/showthread.php4?t=10645&page=251. I wanted it to run on pump gas so I can drive it whenever I want.
2. I wanted it to be mild mannered enough to drive it on the street without hating it.
3. I wanted 650+ hp
4. I wanted 650+ hp with as broad and flat a powerband as possible
5. It needs to be able to run 20-30 min sessions on a road course.
6. I don't want to be tearing it down all the time
I bought the block, heads, intake, carb and oiling system.
Blair listened to what I wanted and said he could do what I wanted. He didn't force me into anything but educated me on the pros and cons of each choice. He built what I wanted not what he wanted me to build. In the end he nailed it and then some.
It isn't 13 to 1 so it's giving up a lot there.
The cam makes more than the power goal I originally wanted but is "small". The lift at the valve is only about .630 well under where max flow of the intake is but also it's easy on the valve train. It also appears to idle with authority but still pretty mild at a reasonable RPM.
The exhaust side of the head suffers from Fords mistake in design. Blair could have fixed it and it would make a lot more hp. I just didn't want to spend the extra $$. He said he could meet my hp goal without filing the floors and he was dead on.
We could have gone bigger on the bore and gained CI but it cleaned up at 4.255 so Blair said leave yourself room for the future we'll still make your hp goal.
All I can say is anything Blair said the motor would do it does. Hearing it on the dyno it just wants to keep running. Smooth as silk it never seems to labor, no hiccups, it just pulls. He brought a 4150 carb he said would run as well or better than my Dominator. I have no reason to think it wouldn't since the one he brought to Jay before did the same thing.
When I first contacted him he said "I like building these things and don't cost any more than a chevy guy" Man that was the truth. He didn't blink an eye about the idea of taking it to Jays dyno to prove what it would do.
I've spent the same or more on heads and machine work before but never got the level of performance. I've seen plenty of stories on forums of problems with parts and machine work. I think as a paying customer it is as important to tell people where they should go to get what they want.
Thanks Blair
