^ +1 forgot about those. and op if your going into the engine i would suggest you pick a custom grind cam to just finish it off

dont waste the time. spend your money wisely by piecing together a good head/cam/intake combination. if you need further advice ask

To play devils advocate, the Dart Jr's do not flow as well as ported E7's. You can make decent power with a matched combo anyday.

There are charts all over the internet. Now, Thumper and Powerheads both report they flow (@.500) approx. 217-219 intake, and 176 (powerhead w/1.6 valve) and 154 thumper with stock valve size. Those are comparable to other Irons, Stock GT40, Dart Jr.

The only way your going to flow more than ported E7, is but a aftermarket head, like TF or AFR. Those flow some serious air.

no use spending money on e7's nevertheless. they make a nice door stop

you got any recommendations for a 83 302? I was thinking about Gt40 or GT40P heads but ive heard they need to be used with the Upper and lower GT40 intake? i would like to keep it carb.

Thanks, appreciate the help

grnstang

no you dont have to use the gt40 intake. use the gt40p or gt40 heads if you want, but buy valve springs and a matching cam look at andersonfordmotorsport.com they sell cam and spring kits, and look at an edelbrock carburated intake and get a holley carb. If you have the cash i would send the heads somewhere to get a valve job and get some port work done, get em cleaned up

sounds good, got the carb and intake already. now i just gotta get the rest i wish i had a pull a part junkyard around here. ill have to make some phonecalls see if they got any heads then ill get em ported and polished... Any idea how much port and polish costs and how much Good heads from a junkyard cost?

Thanks

the only thing you need, is if you get gt-40p's you cant use equal length shorty headers, you can put any intake on top of em. if you wanna make it moderate, the frpp cams work well, like a e cam f cam, i currently run a tfs stage 1. look into a weiand stealth intake and a holly carb.

will long tubes be direct fit?

redpony88

yep LT's will do the trick
