| Post subject: | porting slant heads |
ok guy's what's the do's & don'ts when porting a slant head for street use. i'm looking at a strong street race head. it's not a everyday driver it will be on club rego & just be driven to valiant club meets, out to the drags & weekend cruising. fuel consumption is not a issue. i have ported one slant head last year & it seems to have worked very well. as with all mopar heads i don't take anything off the bottom of the port & bottom of the short radius . what else do i need to know ? i will be looking at using valves in the 1.70in / 1.4 ish range, 500 cfm bbl carb & compression & cam to suit . again it's not a all out drag head but not a daily street driver, 3/4 race is my goal. A body into the 15's is the goal if i can quicker better but gotta keep it real $$$ wise. die grinder is good cheap hp. i will get the head cleaned , crack & sonic tested. i have time on my side & a spare head i can start working on. |

Look at the info in the Engine FAQ section..... some great photos, plus stock cut aways of head so you can see where to be careful when grinding. |

hey thanks they are awesome pic's. i some how missed the top thread bunch of port cutaway photos. i can't wait to have another go now. i also found the port flow # thread as well. that was real interesting also. i wish there were photo's of chamber & bowl after porting. if they are on here i'd love to see them. it looks like as of tonight after seeing the cutaway photo's & called my mate with the slant, i have now got the job of doing a race head for him. this time with time & crack & sonic testing on my side. hopefully the head will see a flow bench. that will help when it's time for my head. btw what 11/32 valves do you guy's use ? if yous use them? thanks a bunch. |
