If they perform anything like mine, you're gonna love em! Instant throttle response throughout the power curve (with my 347 c.i. setup anyway). I swear it was like adding a 75 shot of Nitrous compared to the Windsor Jr's they replaced. Also, the finish of these heads are spectacular! What cc chamber did you get?
Spectacular! They are impressive examples of quality machining! [Almost a piece of art]. I'm glad to see there are a few good machinists still employed! lol
I have the 185's also. They have been ported and milled. I havent had the car on the strip yet but, if they let me, I will run it this spring. At Ford Carlisle I plan on putting it on the chassis dyno.
i love mine they work on a 302 need to check springs the spring pressure were a little low on mine change to a comp spring have ran 3 cams with these heads moved to a solid roller this time the heads just keep making power good luck i think you made a good investment
i have the 62 cc head how much did you mill the head & did you flat mill i did not do any port work because of CNC on them or mill did you run the heads before you P&M them are have flow numbers thanks ivy
I bought them used from a friend who worked at a speed shop that specializes in head work. He said they were angled milled to give 53cc combustion chambers. I don't have the #'s on them but I will ask him next time I see him.
Ford man What cams did you run and what kind of Et did you get out of each one. Im looking for a good solid cam for mine.
the last two were roller comp cams the XE282 HR 35-522-8 this is a fair cam to about 5800 rpm my high gear was flat ran a 11.30 with this cam i went to the solid roller 35-771-8 XR280R-10 &SPRINGS INT608-242 EXH 614-248 THE SOLID ROLLER IS THE WAY TO GO the car has ran 10.88 120 1.462 with a 7000rpm pill one time went back to 6500 rpm runs around 10.95-10.92 it is a stock block 302 i stay with the 6500 rpm the power the solid roller makes is amazing its worth the extra $ i used the doug herbert S roller 199.95 you have to take the heads off to put them in the block (302 no power adders rpm intake 600 holley HP C-4 4700 stall 370 gear thats what the cam calls for 355 to 370 Derek Scott at comp cams you need to talk to him for best suited for your application he is very good on the ford cams if i can help e-mail me thanks Ivy
on my 357w called comp they say for hyd roll the 35-452-8FW 290RF-H is my best choice with there roller lifters and the AFRs and valve changes and stuff that’s been done it should pull a good 6500 with no float or problems was told by the Tech at ARF said the heads should flow around 315-325. 11.3-1 comp using the stealth intake ported was told I should go to at least a 800 or 830 Dbl pumper trying to make the it strong and last the desktop dyno shows it at 536 horse at 6500 with 487 fp torque at 5000 with the 750 carb. Hope the program is as close as they say it is
i tryed two carbs on my 302 750 vac sec and 650 mech with a proform body shiped it to davanci carb they did all their tricks on it didn,t work next step go to page260 HOLLEY BOOK (HOW TO SELECT THE RIGHT CARBURETOR SIZE ??? AIR FLOW VS. ENGINE RPM) the chart said 300cid at 6500rpm =600cfm carb. tryed the 600 HP with 72 jet out of the box dropped 3 tenths if your aint happy with your set up try this it worked for me
I do not have it together to find out the 750 did very good for it before but it was basically stock 351w Interceptor other then hotter cam Lunati Bracket Master II Adv. Duration: 292°/292°Gross Lift: .512''/.512'' With the same intake and MSD distributor and 6Al it ran strong ran with a G-tech. Before the MSD distributor was 13.69the best time put the new MSD distributor and it run 12.87 - 12.92 108-112 mph that was all i did to the engine and it had 143.000 miles on it that’s why the dura spark dist was wore out
thats a good et on your car are you running headers on your 351 maverick i had a 351 w but i never got away from the 302 i sold it the other day needed the room in the shop i use all msd with 40 degree locked i tryed a victor on my car it lost 1/2 sec no bottom end went back to the rpm duel plane intake going to baytown first points race today gona be sunshine 75 deg im ready to rock & roll
There 1 5/8 with H pipe 2 1/2 2 chamber flow masters. All the way out the back using the Vacuum Advance MSD distributor, think its set full 36 deg in by 4000 rpm something like that 0 to 70 it pulled real good then it fell flat after 80 with the engine the way it was that desktop dyno showed 306 hp @ 5000 and 357 fp torque @ 4000 but at 2500 rpm it was already putting out 320 fp torque the program showed reline at 5400rpm so the 380 gears might have been a little much if it could not pull past 5200 rpm and it would not till after the new distributor then it pulled 5700 but it was not happy about it witch is why its tour down now it was fun tuning it trying to get all I could out of it was not bad for a motor with 143.000 miles on it when I pulled it out of the cop car it ran 14.99 and 15 teens in the crown vic it was 4.180lbs but i put 4.10 gears in it with the AOD they was like 3.55's
