DavyZ Posted September 14, 2001 Share Posted September 14, 2001 SWEET! I have been eying the same ones. I really think they are the best. A local speed shop around here says they are worth the "extra" money. I would love to have those on my engine too. Congrats! Davy Quote Link to comment Share on other sites More sharing options...

dmanzo57 Posted September 14, 2001 Share Posted September 14, 2001 Excelent choice. I'm real happy with my AFR190's. Your dad better look out! Don Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted September 14, 2001 Share Posted September 14, 2001 I'd appreciate it if you had those AFR's flowed by a respected local shop when you have a chance. AFR has a bit of a history of inflated advertising numbers. I flowed a set and my rpm's flowed very similarly (had both sets flowed a while back)although published numbers wouldn't have supported the local test results (above .500 lift the AFR's were climbing ahead, but I'm not running a lot above .500). They have various offerings but their were some basic design details including comb. chamber geometry/plug location/angle that were frowned upon by some respected builders. Some LT1 guys have disproven some of the AFR claims as well. Apparently they've changed some details in last couple years but I know the magazine results etc weren't quite right a year or two ago when I looked at them. For higher power building beyond 400hp I'd personally look at brodies/canfields and then AFR's. Others will support the same levels but will need a little more cleanup. Just my .02c and I wish I could recall more detailed info from the discussions on the AFR design specs, (on blown motors they haven't been lasting up here, I do recall that). If I come across my old comparison graph I'll post it up. (FWIW, edelbrock OEM rpm valvesprings are known to be weak and fatique rather early....mine tested out as dead after a year's use including some high revs but noone testing was surprised as they've seen them regularly, I put in all comp cams parts for replacement) Quote Link to comment Share on other sites More sharing options...
z ya Posted September 14, 2001 Author Share Posted September 14, 2001 My dad's 280 is pretty fast with its fast burn 385 sbc and tpi 700r4. Its gonna be fun. We just got done putting in the new comp cam and removed the old heads. The cam is rated at 286 duration and 490 lift. I am running some roller tip summit 1.5 rockers. I am hoping for around 420 to 430 hp without NOS. Quote Link to comment Share on other sites More sharing options...
Guest Fast Frog Posted September 15, 2001 Share Posted September 15, 2001 Good choice!!! CHP has rated AFR heads as one of the very best on the market. I'll be considering a pair for my engine upgrade also! Quote Link to comment Share on other sites More sharing options...
z ya Posted September 15, 2001 Author Share Posted September 15, 2001 I will for sure keep you guys posted. What do you guys think of my motor combo? 350 sbc 10 to 1 comp AFR 195 heads RPM air gap intake 750 holley 1.5 roller tips pro form hei 1 5/8 shortie headers 2.5 delta flows 286/490 comp magnum cam Quote Link to comment Share on other sites More sharing options...
pparaska Posted September 15, 2001 Share Posted September 15, 2001 Sounds Sweet. My guess is 400-425 hp at the flywheel, if not more. Quote Link to comment Share on other sites More sharing options...
silicone boy Posted September 16, 2001 Share Posted September 16, 2001 Great choice. I was lusting after a set of those, but I decided to do it right and get the brakes up to snuff first--400 to 425 hp and rotten stock Z brakes does not sound like a smart idea. Yes, I'm impatient to work on the motor and put the T56 in, but first things first. Good luck Quote Link to comment Share on other sites More sharing options...
John Scott Posted September 16, 2001 Share Posted September 16, 2001 A good choice! I'd hope the "independent" test done by CHP was legit. Flow all the competitve models on the same bench, at the same facility. The 190s outflowed everyone in the 190 class, especially in the lower lift range, not to mention outflowing many of the bigger heads as well. When I get my 383 project rolling, it will have the 195s. Keep us posted on the results. JS Quote Link to comment Share on other sites More sharing options...
