Mines a 94 so the flow rates on the 710's are about as close to stock as you can get, when i get the kegger mod'd and get some more air into her then ill consider jumping up to the 703's. I bought these 710's back in may but just finally got them put in yesterday lol.
I forgot about the different flow rates from 93-95 and 96-98. Sorry.

About a week in and I have nothing but good things to report about the 710's in the 93-95 5.2's. I guess my pcm has balanced out a little bit and i now have a slightly different feel behind the wheel, i certainly have a better throttle response, I'm to 15.9 MPG(from 13.7), and I feel like the engine is running better overall. Perhaps my injectors were just about done, considering that had never been cleaned or service since original installation, but I'm extremely happy with the improvements I'm seeing out of the ole girl

So anyone one got some stats on their mpg after the swap? It all makes sense to me that the mpg would be noticeably better, wouldn't expect anything crazy though. So the average cost for 6 703s would be around $40? Wanna do this so bad!

So you guys know, the overhead is calculated based on flow rate. Since the flow rate is different, the overhead will now be off more than it was before. I gained about 2 mpg according to my overhead, however, I stayed about the same according hand calculations.

Awesome, awesome, awesome! I'm gonna go to the jy hopefully tomorrow to pull off some injectors! I usually get about 21mpg in the summer and about 19mpg in the winter because of the cold. So I should be averaging 20 mpg when I change it over to the 703s. When I get them in, i'll be sure to contribute some data!

Those aren't right.
