Guest Anonymous Posted September 26, 2002 Share Posted September 26, 2002 I really like the SBC that GM puts in Pontiacs. Quote Link to comment Share on other sites More sharing options...
Guest jens Posted September 26, 2002 Share Posted September 26, 2002 The pontiac 350-455 block is the same size but the main bearing diameter is smaller in a 350-400. The exhaust valve is smaller in 74- Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted September 26, 2002 Share Posted September 26, 2002 if possiable start with a 455 or 428, all pontiac v8 engines from 326-455 are the same basic size and weight, now it depends on how much money you want to spend but edelbrock and WENZLER make much better cylinder heads than stock. http://my.execpc.com/~lewenz/schief1.htm heres some info youll need http://www.boyleworks.com/ta400/psp/blockID.html the wensler heads flow better than the pontiac heads so Id use wensler heads and intake then look at what edelbrock got even with their heads out of a 467(bored 455) Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 26, 2002 Share Posted September 26, 2002 wow that is some good info thanks.i want to save a little bit more gas mileage, so i was thinking more along the lines of: pontiac 389ci or 400ci small block with the whole edelbrock performer package (cams,lifters,heads,)but with dual holley 4barrels and a weiland blower. and what compression ratio would be good for forced induction on this engine. im pretty sure the edelbrock heads make for a easy adjustable compression ratio.oh and heavy duty pistons,connecting rods and crank. sound good? what do you guys think?, thanks for the input Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted September 26, 2002 Share Posted September 26, 2002 there is no pontiac (SMALL BLOCK) a 400 is the same size as a 455! no matter what pontiac you build you must replace the connecting rods if you want the engine to live over 6000rpm if it makes good hp as stock pontiac rods are weak. heres some choices http://www.flatlanderracing.com/olivermopar.html http://www.partshp.com/Rods http://www.scatcrankshafts.com/forged4340hbeamrods02.html heres more good info http://www.classicfirebird.com/hand/hand.html http://www.classicfirebird.com/tech/bprint.html http://www.pontiacengines.net/ http://www.teufert.net/pontiac/cranks.htm http://ourworld.cs.com/gaotman428/pontiacengines.htm http://www.highperformancepontiac.com/ Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted September 26, 2002 Share Posted September 26, 2002 if your worried about gas mileage your not interested in a supercharged big inch high performance engine tips (1)use all forged parts (especially the connecting rods and crank.) (2)keep the static compression at about 7.5-8 to 1 ratio (3)use huge port heads with big valves and a cam DESIGNED ESPECIALLY FOR A SUPERCHARGED ENGINE, standard design cam timeing would cost you lots of hp that a supercharger design cam keeps (4)large full length headers and a free flowing exhaust (5) spinning a large supercharger slower works much better than spinning a small supercharger much faster to get your boost (6) intercoolers and timeing retard ignitions are great ideas Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 26, 2002 Share Posted September 26, 2002 im sure you know how a clutch fan works, in short it regulates how fast the fan spins correct?, well anyways has anyone ever made a clutch for a supercharger?. oh and who here has seen the movie mad max the car in the movie had a button that engaged the belt on his supercharger i just thought that was interesting.

Guest Anonymous Posted September 26, 2002 Share Posted September 26, 2002 oh yeah and i am slightly concerned with gas mileage so what are some good small block engines from pontiac or somebody else? thanks for all the great info Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted September 26, 2002 Share Posted September 26, 2002 yeah! its very rare , its called A.... #%*&*&^ 350-383 CHEVY SMALL BLOCK thats why everyone else runs one, less problems, good hp, swap is well known,costs are relatively low, the engine fits and thats why that swap is so popular Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 26, 2002 Share Posted September 26, 2002 ok ok ok i get the picture, but i have a small block chevy question, is tri-power worth it on a 383 sbc with edelbrock performer package? thanks Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted September 26, 2002 Share Posted September 26, 2002 worth it,too who? hp wise no! for looks maybe!you want looks and hp? heres a nice set of webers or EFI Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 27, 2002 Share Posted September 27, 2002 Yeah, tri-powers don't have any horsepower over single quad actually. They do look cool though! I have been toying with the ideal of using a tri-power manifold with three TBI throttlebodies, sorta re-bop-retro fuel injection style. But HP wise, it'd probably be down to what a multiport FI could put out. Regards, Lone Quote Link to comment Share on other sites More sharing options...
