Hi there! Im busy compiling parts for a Chevy 350 sbc street build. I have considered top end bolt on kits, but for reasons unknown im also looking @ custom parts. I know what i want though! Def low end to mid torque, around 400/440 hp. I wont be racing! just pushing the seats back in the streets! I live in Cape Town SA so i have to import so im really trying my best to listen to the hundreds of pieces of info out there! I want to avoid HP cons,pistons etc cos its pricey - im hoping to reach the mid 400's with a top end only build - is that too much to ask? One guy reckons with a single plane edelbrock jr intake, comp cam 306 and larger valve cut STOCK Chevy heads and a Holley 750 double pumper he gets 425HP - can that be true? cos then i can toss the performance heads for that? i think 450hp is the limit for street, more is too much? so far Chevy vortec heads seem best option price/performance wise, any ideas? i want to save as much money. Ill get new/used: carb,intake,cam,springs,cam,blot kit,exhaust headers,distributor on everything else stock(block,crank,pistons,etc. I don't mind spending a little extra for a little extra - even if its just peace of mind. I would happily up my budget IF I HAVE to - otherwise id rather not. ). apparently single plane offers better high end torque where dual plane better low rpm torque? the vortec heads also appear 2b better for low end grunt than higher revving, so good choice number 2? (and whats the diff between bowtie and vortec?) after that cam/carb/intake is easier to choose! ANY suggestions welcome! thanks a mil!
its a stock engine, no idea on tranny yet... im upgrading the suspension with jag stuff. the car is a rather hefty ford cortina XLE form the 70's, 4 door sedan. Ill be strengthening the rear diff aswell for twisting... and better rims/tyres.
sorry, but i think manual definitely? rear diff will be decided when i figure out tyre sizes - and i want a gear for loger distances at lower rpm... ie highway cruising... any gearbox suggestions and what rear suspension i can consider? (Jag xj6/12 @ the mo - quite a few of those around here stripping) - thanks all! and im totalyl for the old school power thing - but im sure machining stock heads would 'almost' cost as much as vortec heads on ebay? (seen some @ $240 / set)
