its a 306 hyperteutic pistons heads are dart windsor jr heads crane roller rockers, i have a friend helping me thats built quite a few engines and he said we could probably get close to 400 hp with it..
You don't think the cam will get there with other parts around it? I think it will for sure. It's not a particularly small cam. Pretty beefy for a flat-hydraulic street cam. I can't get it to model past 6500 rpm. Falls flat on it's face after that. However I got it modeled to 480 hp on a 306. Doesn't mean alot, I know, but it points you in the right direction.
Model that sucker all you want. A 224 degree camshaft in a 302 cubic inch engine won't make 400 hp. Unless your model includes a 100 hp shot of nitrous.
BTW with the Windsor Jr's you will run into plug to header clearance issues on most all Maverick headers.
where are you seeing 224 degree? this is an xe274h.. what can be done to fix the problem with the headers and what headers should i use?
thats what the comp cams website says too.. i downloaded engine analyzer but theres a lot that it doesnt have and im not sure how to put it in cuz a lot of it doesnt make sense to me is there a place where i can just download the specs for certain parts?
Which program did you get? What doesn't it have. The one I got came with tons of stock and aftermarket parts already spec'd. All different manufacturers... Where did you get your program? Folks ask alot where to find on to d'load, and I don't know what to tell. It'd be good info for the members. Also, if there is a specific part that you don't have specs for in the program, you have to seek the info out from catalogs, maker's site, detailed PDF files, and from independent sources like magazines. AFRs are twice the head as the WPs. Of course they are twice the price too.
i downloaded the program from a bittorrent site i just downloaded another one thats v 3.3 pro if that has more ill post a link. the heads i got a good deal on but now im startin to hope that doesnt bite me in the a$$ with the header problem.. well i found a version of engine analyzer 3.3 pro to download its very limited when it comes to intake/carb setups and cams but it works heres the link: http://btjunkie.org/search?ref=torrentscan&q=engine+analyzer
also you recommended the victor jr intake but that seems to be a little out of my rpm range at 3500-8000 and that cam is supposed to drop off around 6000-6500 from what ive been told..
Your original post did not state "XE274". I was referring to the Magnum 274. The XE274 shows a 230 degree intake duration at .050" lift with 236 degrees on the exhaust. THAT camshaft could get you 400 hp. Use the Victor Jr. Don't care what anybody told you about the Victor intake. Use it or you'll be sorry.
so you guys recommend the victor jr and holley 750dp right? ratio do you think you could email your parts folder for engine analyzer? i also found a download for desktop dyno today so im gonna check that out. edit: another thing is it may not be too late to cancel on the windsor jr heads, i was looking at the afr heads and it looks like the 2.02 valves can cause clearance issues with the pistons?
