Need a little input on the AFR 195s. Thinking of getting a set (found on another site) to help wake up my little street engine. I have a set of LT1s ported by a SAM student and never really got a good answer on what they flowed. The seller says the AFRs flow 285/212 which I know my engine could take advantage of along with a set of a set of 1 3/4 long tubes, larger TB (still running 48 mm) and better tuneing. I would have to track down a LT4 intake also. I guess my main question is about my cam (in the sig). This is my daily driver and I want to keep the cam streetable. I know there would probably be a better choice of cams but how much better considering what I mentioned above. My times are ok but can be much better. Consistant 1.78 60 ft times can be improved with a gear change and a little higher stall. Would like to get the best times I can (of course) but 12.0 would tickle me pink. Thoughts? Comments? Am I headed in the right direction? Chime in if you can help.

I can't complain about them, but about 98.5% are gonna tell you to get some LE, AI or PortPro's

 

They're good.... any company that has a 3 month waiting list on average is shouldn't be putting out anything less than expected. The only hard part is waiting.

 

The seller has them on hand. Purchased them new and never installed them. No waiting. I know its a deal considering his asking price. Just kinda wanted to know if the combination sounds right for my goal. Anyone can "spray" into a good ET. I wanna try and do it all motor. The combination is everything.

I have the 195's and like them, they have been cnc'ed though.
I am running about the same size cam as you, just a touch bigger.
My car being a b-body is heavier.
My car is a T56 with 4.56's.
I had 3.73's and it was fine, but a heavy car needs more gear.
My motor is not a stroker either, so that will help you out.
Give you a comparison.
My car is quicker from 60-100 NA than it was with the stock motor on 100 shot.
I say go for it.
Like above some hate AFR, I dont, they worked on my motor rather well.

AFR LT-195- 195cc port-202/160valve-240int/178ex flow

these were measured at .500 lift at 28inches..

science rules... bravado is for tools..

if you're getting a deal on the AFR's... buy them... unless someone
can produce flow numbers with similar port sizes that are superior...

 

They are a great place to start

 

Heads have been CNCed. Build sheet still in the box. Think I'm gonna take the plunge.

Just remember you can always have them touched up if you want the most out of them. That's any cnc head really, but AFR's CNC'ing looks beautiful.

 

^^^ yes they are... I bought the competition series

 

Get em' if they are that good of a deal!!
You need heads to feed that stroker of yours.

 

Hi Mike! Gonna try and get them, then install them before the shoot out! Hey, dont we have a challange to settle?

So are mine. They look great.
