my last post went over like a fart in church.. so I am asking for advise and if you can help great

my engine build is begining but have a few questions from the expirenced 5.0 crowd I have a 93 coupe have not had it long it has holley systemax upper and lower, pro comp dizzy, msd 6al ,70mm tb, 70 mm mass air, bbk cold air, equal length shorty headers... was told 30 lbs injectors ya I know over kill on a stock motor ok here is my questions
1. will my block take a roller cam or do i need to start with a differant block?
2. i have a set of gt 40 heads that have been ported i will be using for now will they help?
3.summit has a rebuild kit with forged aluminum pistons (yay or nay)?
have alot more questions but will start there ...thanks in advance for your help and paitence

 

Hi Randy, nice to hear from you. Fart in church, well all things shall pass...If this is the 93 block from Mustang it is a roller block. For start the ehads will help more than the stock heads. Better heads out their just $$$$. Forged can take some nos. Hyper will be less and can be used. LRS has budget shortblock for $699. Find a set of 24 and maf to match. Can add quite a bit to those. 30 is a bit much. Bubba

 

what is your goal you hope to achieve with your intended combo??? the entire combo listed would be helpful.......hard to put a puzzle together with only a few pieces.

 

my goal would be 300hp or better.. better would be preferred.. I need it for a daily driver want good power..will be working on another motor for the future far as the engine that is in there i can only assume original ..popped a valve cover and it has stamped rockers so questions do arise I have absolutly no history on this car

 

if your working on another motor in the future than this one I wouldn't spend to much on, if the bottom end is okay, just bolt on some heads and slide a new cam in, all the parts you currently have will support 300 rwhp, but without knowing the future size engine you wish to build it's hard to say what to recommend for heads cause, if you wish to not have to buy heads twice you can purchase a set of heads now with your future build in mind or if money isn't an issue later, buy a set of heads now suited to the 302 build and sell them later, if that's the route you wish to go get TW TFS 170 heads and a stage 1 cam and bolt them to the systemmax intake and if the bottom end is okay call it a day, have a dyno tune and you should easily be over 300 rwhp, if the bottom end needs freshening, I'd just hone it, polish the crank and install new cam bearings, freeze/soft plugs and new rings and call it a day, all that'll cost under 500 for what I call an overhauled engine and it'll met your goal without shelling out tons of cash for the time being. I HAVE DONE SUCH FOR A FEW BRACKET RACING FRINDS AND LAST ONE got 400+ passes out of the motor before it spun a bearing.

 

changed plugs wires cap rotor fuel filter air filter idles fine but still missing at 1500 to 2500 rpm

 

Please do not hi-jack the op's thread with a question not related to his topic, create your own thread!! future such posts will be deleted. thank you

 

i am a fan of gt40 heads. you say "ported" but that is pretty broad.... were the exhaust ports done? ported and polished ? opened to a specific gasket size ? the intakes only need a little smoothing in the turns, and matched to a 1250, also the thermactor bump should be removed, and possibly decked for a little more compression along with a multi-angle valve job

do that and with the right parts to support it (stock intake will support it) you can hit 300 on the cheap





what are your plugs gapped at and what plugs did you use ?

 

OK let me start off with THANKS!! guys tore down the top end and it is a roller motor will have it yanked out by tomorrow evening after work you guys helped me make up my mind just to commit and tear it down.. and Bob i got the heads from a friend who owned a speed shop here in florida now retiered he said they where ready to rock but!!
he wont give me all the info i ask for i think he wants to be part of the build and drink beer away from the wife...ok next group of questions....
1. found these pro comp heads with close to the same numbers as TWs....? for half the price yes I know you get what you pay for but better flow then the GTs this motor will eventually go to my grandson when I get boared with it and step up to the next level
2. what makes up the 306?
3.do you want to shoot me for not having my mind made up?

 

LOL
4. is the crank and rods forged or cast on the 93 i know i will find out tomorrow but i dont like suprises
