Guest y2khayabusa Posted March 30, 2002 Share Posted March 30, 2002 I asked this question about canfield vs edelbrock and I was so blown away with the answers, that I felt stupid. How about some input on this comparison (grumpyvette) anyone. Thanks Rob Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted March 30, 2002 Share Posted March 30, 2002 well we went thru this before, heres the flow numbers performer rpm......canfield 223 cc trickflow .200......130/108...145/105.....136/99 .300......183/144...206/146.....191/136 .400......226/169...252/184.....230/163 .500......229/175...288/203.....253/177 .600......232/182...301/219.....254/190 http://www.canfieldheads.com/sbc_2600.html http://www.edelbrock.com/automotive/head_flowdata.html now the formula for figureing potential hp from head flow is flow at max cam lift x .257 x #cylinders= max hp ) so the edelbrock rpms top out at 232 x .257 x 8 = 477hp without port work but the CANFIELDS are 301 x .257 x 8 =619 hp potentially its not a fair comparison because the edelbrocks are for hot street/strip use on a 350 chevy but the canfields , while they can be used on the street are really racing type heads, now canfield does also make a street/strip head,but even that head has a 50hp advantage over the rpm heads. http://www.canfieldheads.com/sbc_2500.html but thats almost the same price as the race type and it still seriously out flows the edelbrock heads, 259 x .257 x8=533hp potentially so either way the canfields win no contest. Id get the larger canfields, true youll lose some low rpm torque with the larger ports lower air velocity at low rpms but they more than make up the differance in high rpm power by having over 140hp more potential. and just for your info a 383 spinning 6500rpm will need a head flowing about 280 cfm to fill the cylinders completely at that rpm so you can see a small head kills high rpm power. btw heres more head flow #s but be carefull which heads your compareing its very common for a head to just be labled (edelbrock or canfield ) without them telling you what part # your looking at!! http://home.earthlink.net/~hennad/results.html http://www.topher.net/~bearman/gmheadcomp.html http://purplesagetradingpost.com/sumner/techinfo/heads1.html http://www.kendrick-auto.com/head_flow_figures.htm Quote Link to comment Share on other sites More sharing options...
Guest needwaymorespeed Posted March 31, 2002 Share Posted March 31, 2002 performer rpm......canfield 223 cc trickflow .200......130/108...145/105.....136/99 .300......183/144...206/146.....191/136 .400......226/169...252/184.....230/163 .500......229/175...288/203.....253/177 .600......232/182...301/219.....254/190 Grumpy where did you get those #s the canfields rock by those #s . when chp flowed the canfield 223 they got different #s .200.......146/114 .300.......206/144 .400.......245/174 .500.......260/182 .600.......266/190 still very good #s and a great head ,is the chp flow bench right or the other?? thes heads also require the use of offset intake rocker arms just a heads up for anyone looking at them Curtis Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted March 31, 2002 Share Posted March 31, 2002 here , from the canfeild site, http://www.canfieldheads.com/sbc_2600.html and those numbers are for heads with a mild pocket port job (something anyone serious does to racing heads) the chp site uses flow # as cast Quote Link to comment Share on other sites More sharing options...
