i am goinig to be building a stroker as soon as i get the cash. i have built two engines in my young lifetime. one stock and one with mild upgrades. so im still new to all of this and have bought several books on performance engines and stroking and blueprinting, etc. i have learned quite a bit from it on how stroking creates torque and compression ratios and cam timing intakes, yadda yadda yadda. BUT!!! i cannot figure out how to pick a cam and heads to match what i want. yes edelbrock and other companies have packages but i dont know if it will produce the results i would like. how can i figure this out? i can get a block and rotating assembly with the stroke already there and everything is matched for the bottom end. but the top end is where the horses come in. my original plan was a 408 because i can get the torque easier than with a 393. but then someone told me a 418 is about the same price and with that i can get even more hp and torque. what im looking for is around 500HP street car with occasional track use. i will be putting in a tko unit with posi and 3.73 gears. i have 275/50/15s in back also. can anyone help with a good cam/head setup. i would like to go with a roller if possible... thanks guys.

jay,Here is my 393w combo, and here is a thread that gives the results - https://mustangsandmore.com/ubb/Forum12/HTML/012682.html 393w Scat 9000 crank Scat H-beam rods JE 14cc dish pistons ARF 205 heads Comp Magnum mechanica lifters, rod, and rockers (1.6 ratio) Vic Jr intake MSD ignition Holley 830HP FPA Headers 1 3/4" primaries, 3" collectors 3" exhasust, with Dr. Gas x-pipe and Borla XS mufflers Solid Cam built by Ed Curtis at Flowtech Induction 11:1 CR, and runs on 93 octane. Lots of power and very streetable, if you ignore the gas mileage. The Tremec 3550 helps with it s fifth gear. randy

thanks. we only have 91 pump gas here in so cal and thats the max i will pay for. so i need something that will run on that octane. yours maybe 10.5:1 or is that still too high? looks like you have a pretty nice setup there! have you taken it to the track yet to see what you run? and how much did you invest into the engine part? also do you only have the msd dist or did you get the whole box setup too? i have a cleveland in my car right now and was wonderin if i could use it or if it would me more cost effective (due to availability of parts) to find a good used or new windsor block? im pretty sure my block is in good condition to use but i havnt seen very many heads or cams, etc to choose from for it....

408. 10-1 compression. Vic jr heads that I cleaned up the ports a bit. perf rpm intake, proformed 750 dp, 1 5/8 headers and a mild (like .586 lift) custom hyd roller. Footbraking with a converter that'l only stall at 2800 and e.t. streets. 3400lb 70 mach Ran a best of 11.39@119. Motor dynod at 519hp and 532 ft/lbs torque. Runs great on 91. Even run 89 in it cause that is all I have in my small town. I am putting this motor in my tubbed fastback though now. Along with 1 3/4 headers, vic jr intake, custom pro systems 950hp and a tranny brake. Hopefully will be in the 10's but still with the same small cam and low compression.------------------ 1970 mach 1 mild 408w 519fwhp 532ft/lbs torque 11.39@119 1970 tubbed narrowed fastback Fairly stock 351c no#'s YET.

that sounds like what im lookin for there john. thanks for the info. i heard the victor heads are for more of a higher rpm range which makes them better for race engines....??? i was looking at the performer rpm heads and a performer air gap manifold because they seem to bee a good choice for the low to mid rpm range. what cam would match them best with a 408 or 418 stroke for a street car? it sure would be nice to get into the 10's!
