Author	Topic: Holley 750DP body w/850 bse plate?
Rustang1 Gearhead Posts: 108 From: Registered: Nov 2000	posted 03-08-2001 12:35 PM I've heard that a popular swap is attaching the 850 base plate to a 750 body. Is this more than a bolt-on, requiring differnt boosters, etc.? And what are the advantages over just putting on a stock 850DP on my motor? I'm running a 351W/clev 4Vheads at 3100# and shifting at 7500. I was wondering if this mod would help in the lower rpm's and still not sacrifice in the uppers compared to a straight 850? ------------------ 1968 Mustang,Clevor,C4 1969 Torino 351C 4spd 1978 F150 460 C6 1978 F150 351W C6 IP: Logged

It would effectively increase the 750's flow to about 780 CFM without over carburating the engine as an 850 might do. You would be better served in purchasing one of Holleys new "race ready" carbs in the 770 to 830 CFM range. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member Fleet of FoMoCo products Moneymaker Bio US Class Nationals link IP: Logged

Everyone I've spoken with that has used the thing has loved it. Good Luck! ------------------ Mike Burch 66 mustang real street 302 4-speed 289 heads 10.63 @ 129.3 http://www.geocities.com/motorcitymustang/cmml/cmml_mburch.html http://www.fortunecity.com/silverstone/healey/367 IP: Logged

With the 4v cleveland heads, you are not going to have much bottom end torque. Unless it's a stroker. IP: Logged
