boss
In reply to what intake I used I am sad to say that I bought one from proproducts only because it was made in china however I did not know that until I opened box and wala it was stamped on bottom.
It does work good but I did clean it up a little. Its a straight Vortec intake, 305 heads didnt have the extra holes for reg intake, wish it would have, sure limits choices.
The rear pad height is 4 inch like the holly vortec, by going with a quadjet insted of my OEM carter I made up for increase in intake height, Carter taller then quad etc.
I had SMI out of long beach do the Quad to 283 specs so I would not drown the motor.
I wanted to make it as stock looking as I could with exception of valve covers and intake bolts...but needing more Omph to bump the 0.60 gap on them plugs I had to drop in the HEI then I needed the K&N flow through etc then it was all bets off but it worked out fine.
Roller rocker @ 1.52 ... valves @ 184. 150. with 58cc. 2.5 ramhorns with 62 hi po/ crossover and oval muffs
All in all I have about 3/8 space left over under the hood
BUT please remember I have every nut and bolt OEM that I removed neatly packed away on shelf so when I get bored..lol I can always go back to Numbers Correct everything...in fact im putting in my hardend seats this weekend in my old stock heads just in case for down the road.
Happy 4th and keep on waving:crazy
