what would be the reliability on an 87' NA witha bridge port, like how many miles would it last and would it make power at?

 

wouldn't last very long. maybe 20-30k miles....

idle at 2000-3000rpm. power at 7k-10k

 

dude have you ever owned one???????

i had a 1st gen with a extended bridge port it idled a 1700-2000rpm power at about 5k-9k (depending on what carby or injection your running) and that was with my long primary system with my old short system it came on earlier but wasnt as good in the hi rpms
it should last at least 100.000kms(90k miles)

the idle you described is more like j-port or pp

 

here I was with the impression, that you can't BP a 6-port

 

You should run a search on this. There was a pretty long thread on bp's reliability somewhere. I think it would present a lot of helpful info. from both sides.

 

Same here, I thought it was impossible (or at least highly impractical) to BP a six port engine.

 

nope LOL... one of my few bad posts

 

sorry i was talking about brigeys in general i had a 12a in 1st gen but i think it is still possible to do it to a 6 port

 

The only time I've ever heard of a BP on a 6port, is during SCCA cometition. Some shady people will BP their 5/6th sleeves, so they sound stock @ Idle, but onces the secondaries open, they have that much more.

If I had some templates, and my engine was still COMPLETELY apart, I'd do that myself.
