there's a seller on eBay called TRE performance that sells AFR 205's for $1750, and nitrous exh port 205's for $1950...

how much extra power would the nitrous exhaust ports help a guy only running 150 hp shot of juice?

Not much for only a 150hp shot.Now if you were spraying 250hp then I would say go for it (or +400ci stroker)

well i doubt i will ever spray that much juice but i will have a 408 or 410W one day. btw should i run a solid roller cam or stay with hydraulic. i will be getting new heads soon i hope.

If its on the street,go with hyd. roller,makes a great cam.

i guess your right. i have a buddy who's uncle has a custom cam shop. i will be giving him all my info and getting a custom grind. i guess i better get a vic jr intake to go with those heads.

Yup Victor Jr. intake is just right for that combo,have it port matched and your go to go.

That was what we were runing for a good amount of time.

408,TFS ported heads,Cam Motion hyd. roller,and Victor Jr with a plate.When never ran the nitrous with the plate though,went to a Super Victor and a fogger.

We did run it n/a however,untuned it went 10.80 @ 125mph befor we added the vacuum pump witch I know after we put it on it helped.It would have gone mid 10's n/a tuned with the vacuum pump.

We still needed to get the suspension worked out as well.

was it a street car? or strictly track. i know guys don't like to give out cam info well atleast guys who race for a living but what kida specs were you running on the cam? if you needed a vacuum pump i assume lots of duration?

Street/strip car,the vacuum pump was because it works better than breathers,helps seal the rings better (whitch reduces oil contamination and that help with detonation also),and it reduced lifter pump up at high rpm (7200rpm was the shift point).

Ill PM you the cam specs later.
