cavboy78 28 Report post Posted December 1, 2015 A little late to the party, but the link below is to my engine build which is similiar to yours. In a nutshell: 351w f4te block bored to 357, rhs 200 heads, comp cam xe274hr, holley 650 dp, FPA longtube headers, T-5z, and 3.89 gears. Engine dyno says ~430/430 and runs great. http://1969stang.com/forum/index.php?/topic/47693-rhs-heads-make-some-power/ Quote Share this post Link to post Share on other sites
J's69Mach1 17 Report post Posted December 2, 2015 Hey Cavboy78, how are the fpa headers,how u like em? Are they 1 3/4" tubes? Quote Share this post Link to post Share on other sites
cavboy78 28 Report post Posted December 2, 2015 they are amazing! Stan is very knowledgeable and easy to work with. He even ensured me that the headers would clear the borgeson steering box (slightly larger in some places) and my clutch cable linkage. They did. Coating is nice and welds are very clean. The flange is thick and has both bolt patterns, which made my life a thousand times easier taking on and off since the rhs heads have both as well. My dad put a set of FPAs on his 57 thunderbird over 10 years ago and still look and work great to this day...one of the reasons i went with fpa on mine. yes, 1/3/4".

J's69Mach1 17 Report post Posted December 2, 2015 Beautiful! That's sounds great cause I have P/S borgeson setup too. That's the headers I am needing . Quote Share this post Link to post Share on other sites

bryonbush 85 Report post Posted September 6, 2016 im going to jump in on this. Right now i have a 351w with performer rpm intake and heads w/ the .202's, try y headers and comp cams CCA-35-421-8, 3.80 posi rear and 4r70w trans, Dougs 1 3/4 headers, 3" pipe. Its sitting at 9.5 compression. not sure the exact power, but i feel it could be more so ive been looking at AFR 205's. will the headers i have now fit with the AFR?

MikeStang 247 Report post Posted September 6, 2016 Don't think the Try-Y's will fit Byron, the exhaust ports are raised and a good bit bigger on the 205's That Comp cam listed is the same one my friend runs in his 408 with Patriot performance Alum heads through a 5 speed and he put 410hp to the ground on a Mustang Dyno Quote Share this post Link to post Share on other sites
