hey all, need your opinions and suggestions, i'm building my engine now, here is my plan so far, bottom end is already all purchased, will be going to the machine shop this week i hope. fully forged 4340 h beam rods, 4340 crank, srp flat top pistons with 5cc valve relieves, thats what i have so far. this is what i want to use: i'm thinking about buying the summit/holly/weiland/vooodoo combo from summit which will come with 670 cfm street avenger carb, stealth manifold, vooodoo cam with duration at .050 233"/241" and lift .538"/.560" part number is SUM-CHLY310 and for the heads i was planning to use Roush 200 heads with single valve springs, part number is WRL-053040-1 with hooker 6901's. for the trans i was going to rebuild the one i have right now in the car with a shift kit and stuff, and use about 3k stall. so what do you guys think? do you suggest anything else? money is an issue here, so any suggestions on my ignition system i'd appresiate, also any recomandations on the shift kit/rebuild kit for my trans?
Sure is a lot of cam for the street. I use an Accel 300+ CD ignition on a 302. Good value. I Like it a lot. Can even use it with the stock dist, but I run an Accel billet unit.
ok ok, i do have a small budget, but i'm still cheap if you know what i mean... but if you have any suggestions on how to get the same stuff alot cheaper please let me know...
I like the TFS twisted wedge or AFR 165 aluminum head better than those 200s.TFS should be really close in price.
Are we assuming its a 302/C4?, I didnt see where it says which block or motor? Would be a killer setup as a 351w Although its too late now, that sounds way over kill for the bottom end. Springs sound on the week side. I would check your spring pressure to make sure, that cam should probably call for double springs.
What kind of compression? Any perticular reason for the high dollar bottom end? Oh yeah it definetly needs a bigger carb.
I would stay with the carb you have chosen, after all alot of the 460s out there were 500 2v, and almost all of the 4v engines had 600 4v w/vaccum secondaries. So if the 670 4v wont feed that 302 with the mods he has listed something is afoot. Major error in engine building is over carberation (I like to call it the 500hp Camaro syndrome) Remember 1 thing-----Bigger is not always better Don
yeap its a 304/c4, i've looked at the tw stuff and it was bit to much for me at this time, reason for high dollar bottom end is its easy to change heads cam and stuff later on in the cars life but rebuilding engine isn't that easy, plus peace of mind helps bout the spring pressure i talked to the summit tech rep, he said that the cam is ok with the springs on those heads
I think the cylinder heads are a little big for that combo I'd do the 165's or windsor jr's. I think the carb will work with a 302 until you get up in compression and camshaft duration.
The only problem with what you did is rotating weight. Piece of mind in nice but like someone said bigger is not always better. Just for talk sake.... Years ago, I built a 400hp motor and had to have the best of the best. I used a forged steel crank and had to have those beautiful sexy Carrillo H beam rods with the SPS rod bolts, oh gosh those things were awesome.... Was my motor strong? HECK yeah!!!..... but it also was about the stupidest thing I have ever done, it had the same rotating weight of some big blocks. Now had I taken all that money and used it on the heads and roller cam I could of made 500hp with no problems.
