It will be a toy, not a daily driver but I would like it to be less of a headache than more of one. I am looking at the Edelbrock 650 AVS and that Holley 750, any recommendations? I've been seeing vacuum based secondaries are better for my C6?

From the bit of research I've done here is what I'm thinking. I may be able to get my hands on some Edelbrock alum 61629 heads which means going to a hydraulic roller setup. I know its not CHI quality but its cheap and better than the low compression 2v irons. - Holley 80508SA 750cfm vacuum secondary (3310 w/ elec choke?) - RPM air gap intake - Edelbrock 7168 cam Eventually convert to electric fan and higher stall converter.

Hey thanks again guys. It was built in late June or July (end of '69 build), would need to see the Martis report again, and has some '70 interior parts. I know its an M code car for sure. The cleveland has a D0Z block, so 1970. I found a link, http://www.karmustang.com/product.php?productid=16146&cat=278&page=1 , that talks about 69's with possible clevelands. Would make a good story if it could be true. My biggest issue is getting the carb/cam/intake and heads all to match up. I got told the block will be my shortfall at about 400hp, I know its got 2 bolt mains when it was rebuilt 20 years ago. I don't know if I could get a 4v head setup to work on this block with a 3.25 gear set and a C6 - I will check out those other sites, a 351c seems interesting to put together Here's a pic - was driving to a wedding. It was originally that jade green and it got painted yellow with satin sport stripes added, boss-ish theme I suppose. (I got it this way) [ATTACH]18228[/ATTACH]

"M" code is a build code, which in 69 meant a 351 windsor and '70 a 351c, here's a source http://www.allfordmustangs.com/forums/classic-talk/96359-1969-mustang-mach-1-m-code-windsor-not.html Its definitely not a 351m from the mid 70's, sorry for the confusion. I'm guessing someone dropped a 351c in here between 69 and 72, I have no idea where the original windsor is. The first thing I need to take care of is the carb, its a 650 Holley, possibly off a truck, from the 80's. Looking at edelbrock 650 avs or maybe a holley demon?

Hey Thanks guys! I will try and look into the engine specs, it came to me through family. Here's the weird part about that engine. I got the Marti report on it and it's a late build '69 and has some original '70 interior parts in it. I also had someone at a show tell me that there is a possibility that this cleveland got shoved in instead of a windsor as the build says 351M only. Apparently they just had crates at the factory saying 351 4bbl not windsor or cleveland. I know that this engine has been in that car since 72. Would be fun to know for sure. I'm concerned that my wife's '12 3.7 auto can take it right now. It has a locking rear end and rev's to the moon, about 3000 rpm at 60mph. I think 3.00 or 3.25? It's going to be a sunday driver, fairly stock look, not a drag racer at this point. Good streetable power would be the goal. Someone had told me the 2v heads limit it to 300hp or so, would like more than that.

Hello all, first timer here. Got a 69 Mach 1 in good shape and I'm looking for some direction in improving it. I'm new to the classic car game here so forgive me. It's a late run 69 build and for some reason has 351 cleveland in it with a C6 instead of a FMX. I'm looking to match up the engine components better as it was put together in the late 80's, with all of 5000 miles on it since then. Currently re-doing the interior but have questions about the engine. The engine is bored .30 over (~357 ci?), 650 Holley double pump carb, clevite 77 brgs, Holley intake of some kind, TRW flat top pistons, ~9:1 compression, 2.5'' headers with (dynamax?) full exhaust, some sort of deep lobe cam, MSD electronic ignition, and 2v cast heads (original 4v's not in great shape) Supposedly the carb, intake, and cam are not matched great. I got told TFS aluminum heads with a matching intake, carb, and cam would be a good bolt setup. I would like to get a different carb, as apparently this stock one is not great, and maybe an intake to get it running better right now. I'm concerned that doing that with the idea of getting better heads down the road would be a waste of $$. Any help/direction would be great, thanks.
